By putting protective filters in place around your network and devices, firewalls can help to prevent a number of different security risks. These can include:
Backdoors. While certain applications are designed to be accessed remotely, others may have bugs that give potential hackers a “backdoor,” or a hidden way to access and exploit the program for malicious purposes. Some operating systems may also contain bugs that provide backdoors for skilled hackers to manipulate to their own benefit.
Denial of service. This increasingly popular type of cyberattack can slow or crash a server. Hackers utilize this method by requesting to connect to the server, which sends an acknowledgment and attempts to establish a connection. However, as part of the attack, the server will not be able to locate the system that initiated the request. Flooding a server with these one-sided session requests allows a hacker to slow down server performance or take it offline entirely. While there are ways firewalls can be used to identify and protect against certain forms of denial of service attacks, they tend to be easily fooled and are usually ineffective. For this reason, it’s important to have a variety of security measures in place to protect your network from different types of attacks.
Macros. Macros are scripts that applications can run to streamline a series of complicated procedures into one executable rule. Should a hacker gain access to your customers’ devices, they can run their own macros within the applications. This can have drastic effects, ranging from data loss to system failure. These executable fragments can also be embedded data attempting to enter your network, which firewalls can help identify and discard.
