1. Claim your winnings or log onto Internet banking via email

Cybercriminals and attackers often hide malware in links in either emails or text messages. Clicking on these links can install malicious software which compromises your computer and gives hackers access to all of your data. These emails are often very convincing, so it pays to be aware.

 

The answer? Don’t click on links in emails from people you don’t know or trust. If it seems suspicious, rather ignore it. This may seem obvious, yet cybercriminals continue to use this method because of its high success rate. Remember, your bank will never email you and ask you to click on a link to log into online banking via email. And if you didn’t enter the competition, or you don’t remember entering it, you haven’t won – things that seem too good to be true generally are.

 

2. Advertise your absence

Standard business practice dictates that when you are away from your desk for any length of time, you should put up an auto responder. However, we often provide far too much information in these emails, such as where we are, how long we will be gone for, who to contact and so on. This gives cybercriminals enough information to launch attacks that can see very convincing and genuine.

 

The best way to avoid this is to limit the information contained in auto-responders, to give cybercriminals less ammunition to work with. 

 

3. Procrastinate your backup

Backups are time consuming, but putting off your backup until tomorrow or the next day could have devastating consequences, especially for small to medium businesses (SMBs). Symantec estimates that during a typical data outage, SMBs can lose 52% productivity and 29% revenue. This can cripple a business, particularly if this data cannot be timeously recovered.

 

Ensure that backup is completed at least once a day, if not more, using an automated backup solution. Identify critical resources, ensure that they are included in backup policies, and importantly, test your backup and restore capabilities frequently to ensure that they are working correctly before a disaster strikes.

 

4. Accept friend requests from people you don’t know

Social media has changed the way we interact with each other, and many people feel that there’s no such thing as too many friends on Facebook. However, making friends with people you don’t know can be a dangerous practice. Cybercriminals use social media to spread viruses, perpetrate fraud, distribute spam and phishing messages, and even gather information that can be used for identity theft.

 

Many SMBs do not have policies in place to regulate social media usage, so it is even more important for individuals to be aware. As a rule of thumb, do not make friends or ‘connect’ with people you don’t know. Social media provides high levels of anonymity, and the person you just made friends with may not be who they say they are.

 

5. Plug in the memory stick you just found lying around

Memory sticks and flash drives are a convenient way of carrying data around, and are highly portable, so are often left lying around. But picking up that USB storage device and plugging it into your computer could be the worst decision you ever made.

 

The drives are convenient for data, so they are also highly convenient for spreading viruses and other malware, and they are often used for just this purpose. Rather spend a few hundred Rand and buy your own brand new flash drive, instead of taking a chance on the one you found lying around.

 

6. Take confidential data home with you

In this age of the mobile workforce, many employees copy confidential data onto unencrypted USB drives, send this information to their personal email addresses or upload them to file sharing sites, in order to allow them to work from home. Many people also remove information in these manners without permission, which leaves the organisation open to vulnerabilities and data loss or theft.

 

If confidential data is needed for mobile working, make sure it is encrypted before it leaves the office, to prevent it from falling into the wrong hands. This way, even if laptops and flash drives get stolen or misplaced, data remains protected.

 

7. Send confidential data over free Wi-Fi

Wi-Fi hotspots are a free, convenient and ever more accessible way of accessing the Internet in public places. However, it needs to be remembered that these hotspots are free to access, which means that they are not encrypted and are typically not secured. Sending confidential information over these channels leaves it open to theft and access by unwanted eyes.

 

If you are going to use an unknown network, it is advisable to use a secured https connection or a Wi-Fi privacy application, which will ensure that your connection over public Wi-Fi is secured, helping to protect data.

 

8. Don’t use the screen lock on your tablet, it’s inconvenient

Mobile devices enable productivity anywhere, and tablet PCs and smartphones have revolutionised the concept of always-on, always connected and always productive. However, the very portable nature of these devices means that they are easy to lose and are often stolen or misplaced. If a device is lost or stolen, it is highly likely that an attempt will be made to breach corporate networks or data.

 

The easiest way to stop casual, opportunistic attacks is to use a simple, built-in feature that is included on every single smartphone and tablet – the screen lock function. Make sure you use this with a strong password or a ‘draw to unlock’ pattern.

 

9. Download mobile apps indiscriminately

Mobile apps can help to increase productivity, and can be used for simple entertainment too. However the simple fact is that cybercriminals follow their audience, and mobile malware has increased dramatically in recent years. The easiest way for attackers to spread this malware is to embed it in an innocent-seeming mobile app, which you as the user then download and install.

 

The solution is to only download apps from legitimate vendors on authorised app marketplaces. Always read the fine print to avoid installing apps that require excessive permissions, such as uploading all of your contacts. These are likely to be malware, which will send out spam and phishing messages and can compromise your device,

 

10. Using weak passwords and the same password for multiple sites

Passwords are surprisingly easy to crack, as most users will choose an easy to remember password about something that is close to them, like a pet’s name. Many people also re-use the same password on multiple sites and write their passwords down.

 

Make sure your password is strong by using at least eight characters and a combination of letters, numbers and symbols. Most importantly, don’t leave your passwords on a sticky note next to your desk.

 

Avoiding these ten simple mistakes can go a long way towards protecting data. However, it is also important to incorporate security best practices into SMB organisations to protect business information. A written security policy is always an advisable first step, and should include aspects such as identification of critical data, strong password policies and a disaster recovery plan. Other areas to look at include encryption of confidential information, development and enforcement of Internet security guidelines, training on security threats, and using a reliable security solution that is kept up to date.

 

Cybercrime continues to thrive, but SMBs are not helpless to protect themselves from harm. Following best practice guidelines and enforcing simple policies to avoid the most common pitfalls will protect you from all but the most persistent attacks, and can help to save your business from security threats and their resultant consequences.
