Do you know that the top 5 causes of security breaches are a lot simpler than you might think? It’s the little things that lead to most security vulnerabilities.
The top 5 causes of network security flaws may seem basic but they’re missed by many and can put your business at risk of attack if not corrected.
Maintaining Patches and Updates
Unpatched machines can give an attacker a clean route into your network. Ensure operating systems, programs and plug ins are updated and patched regularly to protect your systems from known vulnerabilities.
Setting Weak Passwords and Not Changing Passwords At All
Not changing default passwords or using weak passwords can make accessing your systems a lot easier. By creating a strong password you multiply the work the hacker has to do in order to gain access, or in many cases prevent access at all.
Read this guide on how to create strong passwords.
Your firewall rule base could contain outdated rules that are now allowing unauthorised access to your network. The best way to resolve this is to refer to your businesses IT security policy, ensure that all rules adhere to this policy and reflect the aims and goals of it. Regularly review both the rules and the policy to ensure that no changes or updates need to be made, and if they do they are done promptly and thoroughly.
Smartphones, Tablets and BYOD
The increase in smartphones, tablets and BYOD has posed a significant threat to network security in the last few years. These devices store passwords, VPN details, emails and more, data which in the wrong hands could be detrimental to your business.
The solution is to ensure that company data is encrypted, and that encryption is mandatory according to your IT policies.
USB Flash Drives
USB drives are the easiest way for infections to get into a network bypassing the firewall. The best way to ensure that any unwanted visitors don’t gain access via USB flash drives is to restrict which computers can receive these types of storage.
