Network security services are increasingly being implemented by businesses, large and small, in the face of the growing number and variety of Internet threats. Today, nearly all firms are connected to the Internet at least to some extent, and thus are exposed to risks that simply did not exist even a few years ago.
However, many business owners or managers are ignorant both of the full range of cyber-threats and also of the various ways in which these threats could be countered. This is particularly the case in the area of computer network security. You can also look for professionals for network penetration testing at https://engagecybersecurity.com/penetration.html.

If your organization's computer network is connected to the Internet, then it has a real need for network security services to counter the huge expansion in computer viruses, Trojans, spyware, inappropriate material, and "phishing" emails that have burgeoned in recent years.
Information security is a critical area for any business that uses the Internet, and especially those that rely on e-commerce. There are a few main areas of network security services to consider, as follows:
Firewall configuration review, to check that the rules currently followed by the firewall, and the type of firewall used, are appropriate to the given situation.
A detailed audit of computers and devices (such as routers and firewalls), and their location on the network. This includes a review of any DMZ (De-Militarised Zone) standing in front of your organization's core network.
Network vulnerability assessment, to check previously-addressed vulnerabilities to ensure that they are still covered by effective countermeasures.
Penetration testing, to probe the defenses actively for new vulnerabilities. This kind of test should be approached with caution since it has the potential to disrupt operational systems or cause a temporary denial of service. The rules of engagement should be agreed upon in advance and put in writing.
