For an organization to be truly secure, it must protect itself based on security information and event management using a firewall or a combination of cyber security devices.
There are several vulnerabilities and threats that must be avoided using a firewall. However, although there are different types of firewalls, simple use is not enough to guarantee security.
Some firewall use cases include the following risk scenarios:
DETECTING AN INTERNAL ATTACK
The only firewall-based protection against internal attacks is the use of internal firewalls. Used to help protect individual assets on a network, an internal firewall allows organizations to audit sensitive files, folders and documents to detect a possible internal threat.
All audits performed by the internal firewall must be in accordance with the organization's documentation, which describes best practices for using the organization's network.
UPDATE PATCHES AND CONFIGURATION FAILURES
IT solution providers by default discover flaws and develop patches to fix them as quickly as possible. However, the absence or failure to install security patches can cause unprecedented vulnerabilities in organizations.
If users fail to implement these patches, the vulnerability remains available to be exploited. The firewall will be responsible for detecting the lack of updates or problems with the update and notifying its administrators.
It is a methodical, disciplined approach to the design, realization, and technical management. At the core, Systems Engineer helps in the coordination of different teams, testing, and evaluation for the development of design and its implementation for the best output.
PREVENTING DISTRIBUTED DDOS ATTACKS
Basically, a DDoS attack is a malicious attempt to disrupt normal traffic on a target network, overloading the target or its surrounding infrastructure with a flood of traffic. It uses several compromised computer systems as sources of attack traffic.
A DDoS attack is like a traffic jam, preventing regular traffic from reaching the desired destination. The main concern in the mitigation done by the firewall in a DDoS attack is to differentiate between attack and normal traffic.
