Understanding patching

What is patching? 

A patch is a fix to software which is designed to improve its performance and/or address security vulnerabilities. A vulnerability is a "chink in the armour" of software, exposing a weakness which can be exploited, making patching a critical process for businesses to follow.  

Why is patching important?  

By not applying a patch, you might be leaving the door open for malicious software (malware) to compromise your systems. Malware often exploits flaws in a system to do its work. Unpatched defects in software may allow cybercriminals to infect or compromise your device with no action on your part.  

What are hackers interested in when they exploit flaws on your computer? 

  • When flaws are located and exploited, they can give hackers just enough time to download ransomware software (as an example).  
  • Hackers are then able to encrypt all your files, making them unreadable while demanding a ransom to regain access. This information can include your client information which can be used to make your customers targets as well. 

Detecting vulnerabilities and weaknesses in software 

  • Check your server, applications and operating system (e.g. iOS, Windows) provider’s official website for updates.  
  • Vulnerabilities may present as a reduction in system performance, an incomplete security check or incompatibility with other networks and applications. These vulnerabilities make you susceptible to hackers looking for an easy way in.

Preventing Compromises
