Looking for secure (and free) DNS? Quad 9 is your new best friend

  • Those in the security space may already be aware of the secure DNS service provided by Quad9. For those who have not heard of this free service, Quad9 is a public Domain Name System (DNS) service that provides a more secure and privacy-focused alternative to traditional DNS services. DNS is the system that translates human-readable domain names (like www.google.com) into IP addresses that computers use to identify each other on the internet.

    Quad9 is known for its emphasis on security and privacy. It uses threat intelligence from various cybersecurity companies to block access to known malicious websites and protect users from accessing harmful content. When a user makes a DNS query, Quad9 checks the requested domain against a threat intelligence feed, and if the domain is flagged as malicious, Quad9 blocks access to it.

    One notable feature of Quad9 is its commitment to user privacy. Quad9 does not store any personally identifiable information about its users, and it does not sell or share user data.


    Users can configure their devices or routers to use Quad9 as their DNS resolver to take advantage of its security and privacy features. The DNS server addresses for Quad9 are usually and

    The name “Quad9” is derived from the service’s use of four DNS servers in different geographic locations to provide redundancy and improve reliability. Users can configure their devices or routers to use the Quad9 DNS servers, and doing so can offer an additional layer of protection against malware, phishing, and other online threats. It’s important to note that while Quad9 can enhance security, it is not a substitute for other security measures such as antivirus software and good internet security practices, and if you are not using these technologies already, then you are leaving yourself open to compromise.

    I’d strongly recommend you take a look at Quad9. Not only is it fast, but it seems to be extremely solid, and well thought out. If you’re using Cloudflare for your DNS, Quad9 is actually faster.

  • @phenomlab thanks for sharing. this will be very useful for me.

  • @crazycells Agreed. I’m using it now, and have been all afternoon. Super stable and very secure.

  • I’ve been using this service for a couple of days now, and it’s made my internet access so much faster. That alone is a plus, and I never thought there would be a contender for Cloudflare in this area.

    Security experts have urged Android users to delete five apps from their phones immediately over fears they are infected with malware.

    Samsung Galaxy phones are particularly at risk from the nasty bug called Anatsa, which is a banking trojan.

    It is capable of performing actions on a victim’s phone without them knowing, including taking money from their bank account.

    The apps, which had been available on the Google Play Store, are:

    It surprises me (well, actually, dismays me in most cases) that new websites appear online all the time who have clearly spent an inordinate amount of time on cosmetics / appearance, and decent hosting, yet failed to address the elephant in the room when it comes to actually securing the site itself. Almost all the time, when I perform a quick security audit using something simple like the below


    I often see something like this

    Not a pretty sight. Not only does this expose your site to unprecedented risk, but also looks bad when others decide to perform a simple (and very public) check. Worse still is the sheer number of so called “security experts” who claim to solve all of your security issues with their “silver bullet” solution (sarcasm intended), yet have neglected to get their own house in order. So that can you do to resolve this issue ? It’s actually much easier than it seems. Dependant on the web server you are running, you can include these headers.

    Apache <IfModule mod_headers.c> Header set X-Frame-Options "SAMEORIGIN" header set X-XSS-Protection "1; mode=block" Header set X-Download-Options "noopen" Header set X-Content-Type-Options "nosniff" Header set Content-Security-Policy "upgrade-insecure-requests" Header set Referrer-Policy 'no-referrer' add Header set Feature-Policy "geolocation 'self' https://yourdomain.com" Header set Permissions-Policy "geolocation=(),midi=(),sync-xhr=(),microphone=(),camera=(),magnetometer=(),gyroscope=(),fullscreen=(self),payment=()" Header set X-Powered-By "Whatever text you want to appear here" Header set Access-Control-Allow-Origin "https://yourdomain.com" Header set X-Permitted-Cross-Domain-Policies "none" Header set Strict-Transport-Security "max-age=63072000; includeSubDomains; preload" </IfModule> NGINX add_header X-Frame-Options "SAMEORIGIN" always; add_header X-XSS-Protection "1; mode=block"; add_header X-Download-Options "noopen" always; add_header X-Content-Type-Options "nosniff" always; add_header Content-Security-Policy "upgrade-insecure-requests" always; add_header Referrer-Policy 'no-referrer' always; add_header Feature-Policy "geolocation 'self' https://yourdomain.com" always; add_header Permissions-Policy "geolocation=(),midi=(),sync-xhr=(),microphone=(),camera=(),magnetometer=(),gyroscope=(),fullscreen=(self),payment=();"; add_header X-Powered-By "Whatever text you want to appear here" always; add_header Access-Control-Allow-Origin "https://yourdomain.com" always; add_header X-Permitted-Cross-Domain-Policies "none" always; add_header Strict-Transport-Security "max-age=63072000; includeSubdomains;" always;

    Note, that https://yourdomain.com should be changed to reflect your actual domain. This is just a placeholder to demonstrate how the headers need to be structured.

    Restart Apache or NGINX, and then perform the test again.

    That’s better !

    Over the years, I’ve been exposed to a variety of industries - one of these is aerospace engineering and manufacturing. During my time in this industry, I picked up a wealth of experience around processing, manufacturing, treatments, inspection, and various others. Sheet metal work within the aircraft industry is fine-limit. We’re not talking about millimeters here - we’re talking about thousands of an inch, or “thou” to be more precise. Sounds Imperial, right ? Correct. This has been a standard for years, and hasn’t really changed. The same applies to sheet metal thickness, typically measured using SWG (sheet / wire gauge). For example, 16 SWG is actually 1.6mm thick or thereabouts and the only way you’d get a true reading is with either a Vernier or a Micrometer. For those now totally baffled, one mm is around 40 thou or 25.4 micrometers (μm). Can you imagine having to work to such a minute limit where the work you’ve submitted is 2 thou out of tolerance, and as a result, fails first off inspection ?

    Welcome to precision engineering. It’s not all tech and fine-limit though. In every industry, you have to start somewhere. And typically, in engineering, you’d start as an apprentice in the store room learning the trade and associated materials.

    Anyone familiar with engineering will know exactly what I mean when I use terms such as Gasparini, Amada, CNC, Bridgeport, guillotine, and Donkey Saw. Whilst the Donkey Saw sounds like animal cruelty, it’s actually an automated mechanical saw who’s job it is to cut tough material (such as S99 bar, which is hardened stainless steel) simulating the back and forth action manually performed with a hacksaw. Typically, a barrel of coolant liquid was connected to the saw and periodically deposited liquid into the blade to prevent it from overheating and snapping. Where am I going with all this ?

    Well, through my tenure in engineering, I started at the bottom as “the boy” - the one you’d send to the stores to get a plastic hammer, a long weight (wait), a bubble for a spirit level, sky hooks, and just about any other imaginary or pointless tool you could think of. It was part of the initiation ceremony - and the learning process.

    One other extremely dull task was to cut “blanks’’ in the store room from 8’ X 4’ sheets of CRS (cold rolled steel) or L166 (1.6mm aerospace grade aluminium, poly coated on both sides). These would then be used to make parts according to the drawing and spec you had, or could be for tooling purposes. My particular “job” (if you could call it that) in this case was to press the footswitch to activate the guillotine blade after the sheet was placed into the guide. The problem is that after about 50 or so blanks, you only hear the trigger word requiring you to “react”. In this case, that particular word was “right”. This meant that the old guy I was working with had placed the sheet, and was ready for me to kick the switch to activate the guillotine. All very high tech and vitally important - not.

    And so, here it is. Jim walks into the store room where we’re cutting blanks, and asks George if he’d like coffee. After 10 minutes, Jim returns with a tray of drinks and shouts “George, coffee!”. George, fiddling with the guillotine guide responds with “right”…. See if you can guess the rest…

    George went as white as a sheet and almost fainted as the guillotine blade narrowly missed his fingers. It took more than one coffee laden with sugar to put the colour back into his cheeks and restore his ailing blood sugar level.

    The good news is that George finally retired with all his fingers intact, and I eventually progressed through the shop floor and learned a trade.

    The purpose of this post ? In an ever changing and evolving security environment, have your wits about you at all times. It’s not only your organisation’s information security, but clients who have entrusted you as a custodian of their information to keep it safe and prevent unauthorised access. Information Security is a 101 rule to be adhered to at all times - regardless of how experienced you think you are. Complacency is at the heart of most mistakes. By taking a more pragmatic approach, that risk is greatly reduced.

    When you look at your servers or surrounding networks, what exactly do you see ? A work of art, perhaps ? Sadly, this is anything but the picture painted for most networks when you begin to look under the hood. What I’m alluding to here is that beauty isn’t skin deep - in the sense that neat cabling resembling art from the Sistine Chapel, tidy racks, and huge comms rooms full of flashing lights looks appealing from the eye candy perspective and probably will impress clients, but in several cases, this is the ultimate wolf in sheep’s clothing. Sounds harsh ? Of course it does, but with good intentions and reasoning. There’s not a single person responsible for servers and networks on this planet who will willingly admit that whilst his or her network looks like a masterpiece to the untrained eye, it’s a complete disaster in terms of security underneath.

    In reality, it’s quite the opposite. Organisations often purchase bleeding edge infrastructure as a means of leveraging the clear technical advantages, enhanced security, and competitive edge it provides. However, under the impressive start of the art ambience and air conditioning often lies an unwanted beast. This mostly invisible beast lives on low-hanging fruit, will be tempted to help itself at any given opportunity, and is always hungry. For those becoming slightly bewildered at this point, there really isn’t an invisible beast lurking around your network that eats fruit. But, with a poorly secured infrastructure, there might as well be. The beast being referenced here is an uninvited intruder in your network. A bad actor, threat actor, bad guy, criminal…. call it what you want (just don’t use the word hacker) can find their way inside your network by leveraging the one thing that I’ve seen time and time again in literally every organisation I ever worked for throughout my career - the default username and password. I really can’t stress the importance of changing this on new (and existing) network equipment enough, and it doesn’t stop at this either.

    Changing the default username and password is about 10% of the puzzle when it comes to security and basic protection principles. Even the most complex credentials can be bypassed completely by a vulnerability (or in some cases, a backdoor) in ageing firmware on switches, firewalls, routers, storage arrays, and a wealth of others - including printers (which incidentally make an ideal watering hole thanks to the defaults of FTP, HTTP, SNMP, and Telnet, most (if not all of) are usually always on. As cheaper printers do not have screens like their more expensive copier counterparts (the estate is reduced to make the device smaller and cheaper), any potential criminal can hide here and not be detected - often for months at a time - arguably, they could live in a copier without you being aware also. A classic example of an unknown exploit into a system was the Juniper firewall backdoor that permitted full admin access using a specific password - regardless of the one set by the owner. Whilst the Juniper exploit didn’t exactly involve a default username and password as such (although this particular exploit was hard-coded into the firmware, meaning that any “user” with the right coded password and SSH access remotely would achieve full control over the device), it did leverage the specific vulnerability in the fact that poorly configured devices could have SSH configured as accessible to (essentially, the entire planet) rather than a trusted set of IP addresses - typically from an approved management network.

    We all need to get out of the mindset of taking something out of a box, plugging it into our network, and then doing nothing else - such as changing the default username and password (ideally disabling it completely and replacing it with a unique ID) or turning off access protocols that we do not want or need. The real issue here is that today’s technology standards make it simple for literally anyone to purchase something and set it up within a few minutes without considering that a simple port scan of a subnet can reveal a wealth of information to an attacker - several of these tools are equipped with a default username and password dictionary that is leveraged against the device in question if it responds to a request. Changing the default configuration instead of leaving it to chance can dramatically reduce the attack landscape in your network. Failure to do so changes “plug and play” to “ripe for picking”, and its those devices that perform seemingly “minor” functions in your network that are the easiest to exploit - and leverage in order to gain access to neighbouring ancillary services. Whilst not an immediate gateway into another device, the compromised system can easily give an attacker a good overview of what else is on the same subnet, for example.

    So how did we arrive at the low hanging fruit paradigm ?

    It’s simple enough if you consider the way that fruit can weigh down the branch to the point where it is low enough to be picked easily. A poorly secured network contains many vulnerabilities that can be leveraged and exploited very easily without the need for much effort on the part of an attacker. It’s almost like a horse grazing in a field next to an orchard where the apples hang over the fence. It’s easily picked, often overlooked, and gone in seconds. When this term is used in information security, a common parallel is the path of least resistance. For example, a pickpocket can acquire your wallet without you even being aware, and this requires a high degree of skill in order to evade detection yet still achieve the primary objective. On the other hand, someone strolling down the street with an expensive camera hanging over their shoulder is a classic example of the low hanging fruit synopsis in the sense that this theft is based on an opportunity that wouldn’t require much effort - yet with a high yield. Here’s an example of how that very scenario could well play out.

    Now, as much as we’d all like to handle cyber crime in this way, we can’t. It’s illegal 🙂

    What isn’t illegal is prevention. 80% of security is based on best practice. Admittedly, there is a fair argument as to what exactly is classed as “best” these days, although it’s a relatively well known fact that patching the Windows operating system for example is one of the best ways to stamp out a vulnerability - but only for that system that it is designed to protect against. Windows is just the tip of the iceberg when it comes to vulnerabilities - it’s not just operating systems that suffer, but applications, too. You could take a Windows based IIS server, harden it in terms of permitted protocols and services, plus install all of the available patches - yet have an outdated version of WordPress running (see here for some tips on how to reduce that threat), or often even worse, outdated plugins that allow remote code execution. The low hanging fruit problem becomes even more obvious when you consider breaches such as the well-publicised Mossack Fonseca (“Panama Papers”). What became clear after an investigation is that the attackers in this case leveraged vulnerabilities in the firm’s WordPress and Joomla public facing installations - this in fact led to them being able to exploit an equally vulnerable mail server by brute-forcing it.

    So what should you do ? The answer is simple. It’s harvest time.

    If there is no low-hanging fruit to pick, life becomes that much more difficult for any attacker looking for a quick “win”. Unless determined, it’s unlikely that your average attacker is going to spend a significant amount of time on a target (unless it’s Fort Knox - then you’ve have to question the sophistication) then walk away empty handed with nothing to show for the effort. To this end, below are my top recommendations. They are not new, non-exhaustive, and certainly not rocket science - yet they are surprisingly missing from the “security 101” perspective in several organisations.

    Change the default username and password on ALL infrastructure. It doesn’t matter if it’s not publicly accessible - this is irrelevant when you consider the level of threats that have their origins from the inside. If you do have to keep the default username (in other words, it can’t be disabled), set the lowest possible access permissions, and configure a strong password. Close all windows - in this case, lock down protocols and ports that are not essential - and if you really do need them open, ensure that they are restricted Deploy MFA (or at least 2FA) to all public facing systems and those that contain sensitive or personally identifiable information Deploy adequate monitoring and logging techniques, using a sane level of retention. Without any way of forensic examination, any bad actor can be in and out of your network well before you even realise a breach may have taken place. The only real difference is that without decent logging, you have no way of confirming or even worse, quantifying your suspicion. This can spell disaster in regulated industries. Don’t shoot yourself in the foot. Ensure all Windows servers and PC’s are up to date with the latest patches. The same applies to Linux and MAC systems - despite the hype, they are vulnerable to an extent (but not in the same way as Windows), although attacks are notoriously more difficult to deploy and would need to be in the form of a rootkit to work properly Do not let routers, firewalls, switches, etc “slip” in terms of firmware updates. Keep yourself and your team regularly informed and updated around the latest vulnerabilities, assess their impact, and most importantly, plan an update review. Not upgrading firmware on critical infrastructure can have a dramatic effect on your overall security. Lock down USB ports, CD/DVD drives, and do not permit access to file sharing, social media, or web based email. This has been an industry standard for years, but you’d be surprised at just how many organisations still have these open and yet, do not consider this a risk. Reduce the attack vector by segmenting your network using VLANS. For example, the sales VLAN does not need to (and shouldn’t need to) connect directly to accounting etc. In this case, a ransomware or malware outbreak in sales would not traverse to other VLANS, therefore, restricting the spread. A flat network is simple to manage, but a level playing field for an attacker to compromise if all the assets are in the same space. Don’t use an account with admin rights to perform your daily duties. There’s no prizes for guessing the level of potential damage this can cause if your account is compromised, or you land up with malware on your PC Educate and phish your users on a continual basis. They are the gateway directly into your network, and bypassing them is surprisingly easy. You only have to look at the success of phishing campaigns to realise that they are (and always will be) the weakest link in your network. Devise a consistent security and risk review framework. Conducting periodic security reviews is always a good move, and you’d be surprised at just what is lurking around on your network without your knowledge. There needn’t be a huge budget for this. There are a number of open source projects and platforms that make this process simple in terms of identification, but you’ll still need to complete the “grunt” work in terms of remediation. I am currently authoring a framework that will be open source, and will share this with the community once it is completed. Conduct regular governance and due diligence on vendors - particularly those that handle information considered sensitive (think GDPR). If their network is breached, any information they hold around your network and associated users is also at risk. Identify weak or potential risk areas within your network. Engage with business leaders and management to raise awareness around best practice, and information security. Perform breach simulation, and engage senior management in this exercise. As they are the fundamental core of the business function, they also need to understand the risk, and more importantly, the decisions and communication that is inevitable post breach.

    There is no silver bullet when it comes to protecting your network, information, and reputation. However, the list above will form the basis of a solid framework.

    Let’s not be complacent - let’s be compliant.

    The recent high profile breaches impacting organisations large and small are a testament to the fact that no matter how you secure credentials, they will always be subject to exploit. Can a password alone ever be enough ? in my view, it’s never enough. The enforced minimum should be at least with a secondary factor. Regardless of how “secure” you consider your password to be, it really isn’t in most cases – it just “complies” with the requirement being enforced.

    Here’s classic example. We take the common password of “Welcome123” and put it into a password strength checker
    According to the above, it’s “strong”. Actually, it isn’t. It’s only considered this way because it meets the complexity requirements, with 1 uppercase letter, at least 8 characters, and numbers. What’s also interesting is that a tool sponsored by Dashlane considers the same password as acceptable, taking supposedly 8 months to break
    How accurate is this ? Not accurate at all. The password of “Welcome123” is in fact one of the passwords contained in any penetration tester’s toolkit – and, by definition, also used by cyber criminals. As most of this password combination is in fact made up of a dictionary word, plus sequential numbers, it would take less than a second to break this rather than the 8 months reported above. Need further evidence of this ? Have a look at haveibeenpwned, which will provide you with a mechanism to test just how many times “Welcome123” has appeared in data breaches

    Why are credentials so weak ?

    My immediate response to this is that for as long as humans have habits, and create scenarios that enable them to easily remember their credentials, then this weakness will always exist. If you look at a sample taken from the LinkedIn breach, those passwords that occupy the top slots are arguably the least secure, but the easiest to remember from the human perspective. Passwords such as “password” and “123456” may be easy for users to remember, but on the flip side, weak credentials like this can be broken by a simple dictionary attack in less than a second.

    Here’s a selection of passwords still in use today – hopefully, yours isn’t on there
    We as humans are relatively simplistic when it comes to credentials and associated security methods. Most users who do not work in the security industry have little understanding, desire to understand, or patience, and will naturally choose the route that makes their life easier. After all, technology is supposed to increase productivity, and make tasks easier to perform, right ? Right. And it’s this exact vulnerability that a cyber criminal will exploit to it’s full potential.

    Striking a balance between the security of credentials and ease of recall has always had it’s challenges. A classic example is that networks, websites and applications nowadays typically have password policies in place that only permit the use of a so-called strong password. Given the consolidation and overall assortment of letters, numbers, non-alphanumeric characters, uppercase and lowercase, the password itself is probably “secure” to an acceptable extent, although the method of storing the credentials isn’t. A shining example of this is the culture of writing down sensitive information such as credentials. I’ve worked in some organisations where users have actually attached their password to their monitor. Anyone looking for easy access into a computer network is onto an immediate winner here, and unauthorised access or a full blown breach could occur within an alarmingly short period of time.

    Leaked credentials and attacks from within

    You could argue that you would need access to the computer itself first, but in several historical breach scenarios, the attack originated from within. In this case, it may not be an active employee, but someone who has access to the area where that particular machine is located. Any potential criminal has the credentials – well, the password itself, but what about the username ? This is where a variety of techniques can be used in terms of username discovery – in fact, most of them being non-technical – and worryingly simple to execute. Think about what is usually on a desk in an office. The most obvious place to look for the username would be on the PC itself. If the user had recently logged out, or locked their workstation, then on a windows network, that would give you the username unless a group policy was in place. Failing that, most modern desk phones display the name of the user. On Cisco devices, under Extension Mobility, is the ID of the user. It doesn’t take long to find this. Finally there’s the humble business card. A potential criminal can look at the email address format, remove the domain suffix, and potentially predict the username. Most companies tend to leverage the username in email addresses mainly thanks to SMTP template address policies – certainly true in on premise Exchange environments or Office 365 tenants.

    The credentials are now paired. The password has been retrieved in clear text, and by using a simple discovery technique, the username has also been acquired. Sometimes, a criminal can get extremely lucky and be able to acquire credentials with minimal effort. Users have a habit of writing down things they cannot recall easily, and in some cases, the required information is relatively easily divulged without too much effort on the part of the criminal. Sounds absurd and far fetched, doesn’t it ? Get into your office early, or work late one evening, and take a walk around the desks. You’ll be unpleasantly surprised at what you will find. Amongst the plethora of personal effects such as used gym towels and footwear, I guarantee that you will find information that could be of significant use to a criminal – not necessarily readily available in the form of credentials, but sufficient information to create a mechanism for extraction via an alternative source. But who would be able to use such information ?

    Think about this for a moment. You generally come into a clean office in the mornings, so cleaners have access to your office space. I’m not accusing anyone of anything unscrupulous or illegal here, but you do need to be realistic. This is the 21st century, and as a result, it is a security measure you need to factor in and adopt into your overall cyber security policy and strategy. Far too much focus is placed on securing the perimeter network, and not enough on the threat that lies within. A criminal could get a job as a cleaner at a company, and spend time collecting intelligence in terms of what could be a vulnerability waiting to be exploited. Another example of “instant intelligence” is the network topology map. Some of us are not blessed with huge screens, and need to make do with one ancient 19″ or perhaps two. As topology maps can be quite complex, it’s advantageous to be able to print these in A3 format to make it easier to digest. You may also need to print copies of this same document for meetings. The problem here is what you do with that copy once you have finished with it ?

    How do we address the issue ? Is there sufficient awareness ?

    Yes, there is. Disposing of it in the usual fashion isn’t the answer, as it can easily be recovered. The information contained in most topology maps is often extensive, and is like a goldmine to a criminal looking for intelligence about your network layout. Anything like this is classified information, and should be shredded at the earliest opportunity. Perhaps one of the worst offences I’ve ever personally experienced is a member of the IT team opening a password file, then walking away from their desk without locking their workstation. To prove a point about how easily credentials can be inadvertently leaked, I took a photo with a smartphone, then showed the offender what I’d managed to capture a few days later. Slightly embarrassed didn’t go anywhere near covering it.

    I’ve been an advocate of securing credentials for some time, and recently read about the author of “NIST Special Publication 800-63” (Bill Burr). Now retired, he has openly admitted the advice he originally provided as in fact, incorrect

    “Much of what I did I now regret.” said Mr Burr, who advised people to change their password every 90 days and use obscure characters.

    “It just drives people bananas and they don’t pick good passwords no matter what you do.”

    The overall security of credentials and passwords

    However, bearing in mind that this supposed “advice” has long been the accepted norm in terms of password securuty, let’s look at the accepted standards from a well-known auditing firm

    It would seem that the Sarbanes Oxley 404 act dictates that regular changes of credentials are mandatory, and part of the overarching controls. Any organisation that is regulated by the SEC (for example) would be covered and within scope by this statement, and so the argument for not regularly changing your password becomes “invalid” by the act definition and narrative. My overall point here is that the clearly obvious bad password advice in the case of the financial services industry is negated by a severely outdated set of controls that require you to enforce a password change cycle and be in compliance with it. In addition, there are a vast number of sites and services that force password changes on a regular basis, and really do not care about what is known to be extensive research on password generation.

    The argument for password security to be weakened by having to change it on a frequent basis is an interesting one that definitely deserves intense discussion and real-world examples, but if your password really is strong (as I mentioned previously, there are variations of this which are really not secure at all, yet are considered strong because they meet a complexity requirement), then a simple mutation of it could render it vulnerable. I took a simple lowercase phrase


    The actual testing tool can be found here. So, does a potential criminal have 26 nonillion years to spare ? Any cyber criminal who possesses only basic skills won’t need a fraction of that time as this password is in fact made up of simple dictionary words, is all lowercase, and could in fact be broken in seconds.

    My opinion ? Call it how you like – the password is here to stay for the near future at least. The overall strength of the password or credentials stored using MD5, bCrypt, SHA1 and so on are irrelevant when an attacker can use established and proven techniques such as social engineering to obtain your password. Furthermore, the addition of 2FA or a SALT dramatically increases password security – as does the amount of unsuccessful attempts permitted before the associated account is locked. This is a topic that interests me a great deal. I’d love to hear your feedback and comments.
