The fear of losing control of your computer network results in good security practices, but it also leads to half truths about security being shared.

And when myths about computer security begin to circulate, they soon begin to take on a voice of authority. This results in businesses taking these myths as facts and concentrating resources on areas of computer security where it’s not necessary.

To help you avoid falling into this scenario, I’m going to show you the 4 biggest myths of computer security.

1. All Security Threats Are External

It’s common to assume that all security threats originate from outside your organisation, but the truth is that sometimes the biggest threats are within your business. After all, those individuals that already work for your company have much freer access to your systems.

And this takes them one step closer to accessing your secure data without all the hassle of breaking through firewalls etc. Therefore, in the case of a security breach you also need to look at your own employees as, for example, an individual who was missed out on a promotion can easily become aggrieved enough to seek revenge.

2. One Piece of Software Is All You Need

Too often, businesses feel safe in the knowledge that they have an amazing piece of software which is a one stop shop for all their security needs. And, yes, this type of software certainly makes things look neat and tidy, but what if a security flaw is discovered in that piece of software? Suddenly, all your security practices are at risk.

In order to avoid this, you should aim to have different pieces of software in place to deal with security threats e.g. firewalls, antivirus, mail wash etc. With this setup you can rest assured that it’s much harder for hackers to carry out a theft of all your data at once.

3. Windows Is Not Safe

Windows 10 has certainly come in for criticism regarding security and this has led many critics of Microsoft claiming that Windows is a liability in terms of security. However, this is a little unfair.

Whilst PCs running Windows are certainly at risk of more cyber-attacks than Macs, Microsoft are constantly monitoring security threats and issuing patches when necessary. What’s particularly unsafe about Windows is its users.

And this is because users of Windows ignore automatic updates too often. Perhaps this is because they’re too busy checking Facebook, but if they’re not careful their Facebook, and much worse, will be hacked before they know it.

4. Computer Security Is Too Confusing

Many PC users struggle to deal with security threats as they’re very defeatist when it comes to learning about the basics of computer security.  And it’s not a surprise when you consider the amount of technical jargon involved.

However, the basics of computer security aren’t too confusing, so there’s no excuse for not getting to grips with them. If your staff members are able to embrace the core concepts of computer security – good password practices, understanding the threat of email attachments – you’ll find that the risk of succumbing to an attack is reduced.

7 Tell-tale Signs That You’ve Been Hacked

Anyone who sets foot online these days is at risk of falling victim to hackers, so it’s a good idea to know when you’ve been hacked.

After all, the sooner you realize you’ve been hacked, the sooner you can start working to remove the infection from your PC and make your data secure again. However, hackers are stealthy individuals and you may have to look a little closer than usual to catch them in the act.

And, to give you a helping hand, here are 7 tell-tale signs that you’ve been hacked.

1. Slow Internet Connection

If you internet connection has ground to a halt then this could indicate that you’ve been hacked. Due to an increase in network activity – caused by hackers using your bandwidth to commit malicious activity – this can render your normal internet access next to useless.

2. Unusual Access Times

It’s always a good idea to keep an eye on the times at which your network is accessed by new connections. In general, access during your normal working hours is to be expected, but new connections outside these times should be treated as suspicious. Hackers, you see, are likely to use automated software that is active throughout the entire day rather than between 9-5.

3. Disabled Antivirus

There are very few occasions that you would deliberately disable your antivirus, so if you notice that your antivirus software has been disabled this should start ringing alarm bells. And, for a hacker, if they’re able to disable your antivirus software, this allows them free rein to download all sorts of malware to your PC.

4. Unable to Log on?

One of the first things a hacker will try to alter on your system is your login credentials as this restricts your access and gives them more time to cause trouble. Therefore, if you’re absolutely sure that you’re entering the correct username/password combination, you need to consider that you may have been hacked.

5. Strange Cursor Movements

Due to hardware and software issues, your mouse may occasionally move without any user interaction. However, these are usually haphazard movements and certainly don’t double click on programs to open them. If you ever see your mouse ‘come to life’ on its own then it’s time to shut your PC down and call in the experts!

6. Fake Antivirus Messages

You should always make sure that your network users are aware of the antivirus software that you’re running; this is because one way that hackers can target your PCs is through fake antivirus messages. These will usually advise users that a virus scan has been run and viruses detected that only this piece of software can remove. And this will involve being redirected to a website to download the “antivirus software”, but in reality you’ll be downloading nothing but malware.

7. Internet Searches Redirected

Hackers are keen to disrupt your activity for their own benefits and one way to do this is to redirect your internet searches to alternate websites. So, if you find your internet searches suddenly start taking you to dubious websites then there’s a good chance you’ve been hacked.

6 Tips for Browsing Online Safely and Securely

Almost every business has a daily need to go online and interact with the internet, but to do this safely you need a little bit of browsing know-how.

Whilst most websites are relatively secure, it’s difficult to guarantee just how secure they are. And seeing as even government websites can be hacked, how do you know that, for example, that customer maintenance portal you have to log on to daily hasn’t been hacked for dubious means?

Avoiding this sort of scenario is crucial for your business to run smoothly, so I’ve prepared 6 tips to help you browse online safely and securely.

1. Use HTTPS Security

If a website is truly secure then its web URL should start “HTTPS:” and the “S” at the end stands for secure – provided by secure sockets layer (SSL) security. Conversely, if the web URL only starts “HTTP:” then the security behind it will be much less and can’t be taken for granted.

2. Avoid Public WiFi

NEW YORK, NY - JULY 11: A free Wi-Fi hotspot beams broadband internet from atop a public phone booth on July 11, 2012 in Manhattan, New York City. New York City launched a pilot program Wednesday to provide free public Wi-Fi at public phone booths around the five boroughs. The first ten booths were lit up with Wi-Fi routers attached to the top of existing phone booths, with six booths in Manhattan, two in Brooklyn, and one in Queens. Additional locations, including ones in the Bronx and Staten Island, are to be added soon. (Photo by John Moore/Getty Images)

Public WiFi may provide a fantastic service and serve many happy consumers, but unfortunately these networks have a less than amazing level of security protecting them. And hackers are able to easily infiltrate these networks with basic software to hijack the personal data of those accessing the public network.

3. Don’t Click on Phishing Websites

Phishing is a contemporary threat to your data and appears to be showing no signs of going away soon. This is why you need to be on your guard about phishing websites as they can be deceptive beasts at the best of times.

Links to these websites are usually emailed, but whilst the link may appear to seem innocent, it’s possible to engineer a link which reads www.amazon.com but redirects you to a different (and more dangerous) website.

This puts you at risk of infection and having your networks breached, so double check any suspicious links by hovering your mouse cursor over them to get a preview of the true web address.

4. Update Your Browser

Keeping your software up to date is vital to ensure that you’re well protected against hackers who have discovered vulnerabilities in that piece of software. And web browsers are no different, in fact, once support for out-dated web browsers is discontinued, hackers will discover vulnerabilities very quickly.

Therefore, it’s essential that you install all patches and updates as soon as possible to keep your browsing activity protected.

5. Disable Stored Passwords

Although activating the ‘store your passwords’ option may feel as though it’s going to make forgotten passwords a thing of the past, it can actually cause more trouble than it’s worth. You see, if your system becomes compromised by hackers, they can then access all your store passwords.

And the best way to avoid this is to work on a little bit of memory training to remember your passwords!

6. Have a Strong Arsenal

Perhaps the best way to browse online safely and securely is to arm yourself with the best defenses possible. And the more defenses the better.

So, instead of just securing your network with a state of the art firewall, why not try adding in state of the art email filtering? And, you know what, if you also install web filtering software on top of that, you’re going to find your data becomes safer than ever before.

7 Security Tips to Keep Your Passwords Secure

Passwords can easily be hacked and this seems to be happening more and more often, so understanding how to secure your passwords is vital.

Although passwords have come in for a lot of criticism recently, they still have a place in the security arsenal of all businesses. This is why it’s crucial that you don’t underestimate their potential for letting a hacker in the back door.

Aside from using a password manager, it’s actually surprisingly simple to keep your passwords secure, but you’d be surprised by just how many people fail to protect them. And, when this happens, you get hacked!

Let’s take a look at 7 security tips to help keep your passwords secure.

1. Don’t Advertise It!

Yes, that’s right, you have to keep your password secret or it defeats the point of a password! Don’t tell work colleagues what it is and don’t write it down on a post-it note!

2. Different Passwords for Different Accounts

It may seem simpler to use one password across multiple accounts, but this actually puts you at a huge risk of losing all your data. If, for example, a hacker gains access to your email password, their next step will be to try that password in every piece of software you log into.

However, by using different passwords across different accounts, you minimize just how catastrophic the theft of a password can be.

3. Combination Passwords

You should always make sure that you use a combination of letters, numbers and symbols to create your passwords. By using a mixture of these characters you’re ensuring that standard words from dictionary lists will be useless when trying to hack a password by brute force e.g. antarctica will be in a dictionary list, but antarctica247! most definitely will not be!

4. Don’t Make it Personal

It’s very common for people to use their personal details as the basis for their password e.g. name, date of birth, hometown information. However, although this is personal to you, it’s also very easy for hackers to research. And that’s why you need to give the hackers something harder to think about.

5. Longer Passwords are Better

Hackers are able to employ software which uses brute force to check around 2 billion password combinations in one second. And, when you consider that a 6 letter password has just over 3 billion possible combinations, you can see that longer passwords offer more protection e.g using 8 letters produces a possible 208 billion combinations!

6. Regularly Update Passwords

Complacency is the biggest threat to your password’s security. Sure, you may have a password with no personal links and it’s 23 characters long, but give a hacker enough time and they’ll crack it. That’s why you need to regularly change your passwords to make sure that you keep resetting the progress of potential hackers.

7. Enter your Password Discreetly

Always make sure that no one is watching your fingers fly across the keyboard as you enter your password. Okay, no one wants to accuse their co-workers of any bad intentions, but insider threats to data security are a real thing, so always make sure enter your password safely.
