Network Security Services plus your Business

Network security services are getting implemented by businesses, small and large, in the face of the growing number and variety of Internet threats. Today, nearly all firms are linked to the Internet at the very least to some degree, and thus have confronted risks that simply did not exist a good number of years ago. However, many business owners or managers are ignorant both of the complete array of cyber-threats, and also from the ways that these threats might be countered. This is particularly the truth around computer network security.

Should your organisation's computer network is connected to the Internet, it has a real dependence on network security services to counter the huge expansion in computer viruses, Trojans, spyware, inappropriate material and "phishing" emails who have burgeoned in recent times. Information security is really a critical area for any business which uses the world wide web, especially the ones that depend upon e-commerce. There are many main aspects of network security services to take into consideration, the next:

Firewall configuration review, to check that the rules currently then the firewall, and the kind of firewall used, work to the given situation.

Detailed audit of computers and devices (including routers and firewalls), in addition to their location on the network. This includes a review of any DMZ (De-Militarised Zone) standing in front of your respective organisation's core network.

Network vulnerability assessment, to check on previously-addressed vulnerabilities to ensure that they're still protected by effective countermeasures.

Penetration testing, to probe the defences actively for new vulnerabilities. These kinds of test ought to be approached with caution, because it has the potential to disrupt operational systems or spark a temporary denial and services information. The principles of engagement ought to be agreed upfront and put in writing.

These functions may be provided by an in-house team (when it comes to larger organisations) otherwise may be outsourced to some specialist information security firm. In any case, it is imperative that network security services are implemented at regular intervals, and also after any major changes to the network.

The gateway in your internal network is actually the firewall. However, there is a large amount more to network security services than only a firewall. Also involved are considerations including the following:

Network configuration: Is there a DMZ? What Internet-facing computers and servers exist? Type and number of devices: A choice of whether to work with a hub, a switch or perhaps a router may have security implications, as will the question of the items type of cabling has been installed.

Protocols and ports supported: If the network supports services and open ports (like "Telnet" on port 23) which are not actually required by your organisation, chances are they'll must be disabled for security reasons. Auditing and monitoring facilities: Exist logs of network activity and therefore are they in the form that may simply be scanned by the human?

Clearly, there is certainly a lot more to data center colocatoin than installing a firewall having its default configuration enabled. It is really an part of information security that will need reveal level of technical expertise, along with a computer security specialist should oversee the deployment and configuration of your organisation's network.
