How can firewalls be bypassed?

Luetta Kobpal

Well, as an everyday user of social media platforms, I don't know much about how firewalls work or how they can be bypassed. Nonetheless, after conducting some research, I came across some ways that hackers use to circumvent firewalls.

One common method is called "tunneling," which involves creating a secure and encrypted channel through a firewall. This approach uses network protocols, such as HTTPS, SSL, or TLS, to create an encrypted connection that can bypass the firewall's security control. Hackers can use this technique to access restricted content or steal sensitive information, as the traffic is hidden within the encrypted tunnel.

Another way that firewalls can be bypassed is by using exploit kits or malware that can evade security software. These kits or malware can change their code frequently, so firewalls can't detect them. Once malware gets access to a computer, it can access information outside the company's network, creating a "backdoor" that hackers can use to enter the system unseen.

Another technique to bypass firewalls is by exploiting trusted connections or networks. For example, some organizations may permit specific IP addresses to bypass the firewall, or certain software to communicate with outside networks, thinking that it's safe. However, hackers can exploit these trusted networks to bypass the firewall and gain unauthorized access to sensitive information.

Additionally, some attackers may use covert communication channels, such as steganography, to bypass firewalls. Steganography involves embedding hidden messages within images or videos, which can pass the firewall's security scanners undetected. Once the attacker gets access to the encoded information, they can use it to initiate attacks on the firewall's security systems.

In conclusion, bypassing firewalls is a massive challenge that hackers are continually trying to overcome. As users of social media, we should practice good IT hygiene, such as keeping our software up-to-date and avoiding opening suspicious links or emails. Also, companies need to remain vigilant and implement multi-layer security measures to detect and prevent attacks on their networks and assets. Only by being prepared and proactive can we stay one step ahead of malicious actors who are always looking for ways to exploit security vulnerabilities.
