IT Network Security
Thursday, April 22nd, 2010Network security is a self-contradicting philosophy where you need to give absolute access and at the same time provide absolute security. Any enterprise needs to secure itself from two types of access of information: internal access and external access. Securing the access of information or resources from the external world is quite a task to master that is where the need for firewalls comes in. The firewalls act as gatekeepers. It segregates the intrusive and non-intrusive requests and allows access of information. Configuring & maintaining a firewall is by itself a task, which needs experience and knowledge. There are no hard and fast rules to instruct the firewalls, it depends on the source of firewall installation and how the enterprise intends to provide access to information/resources.
Every organization providing outsourced software development services needs to decide for itself that where they need to be between the two extremes of total security and total access. A policy needs to articulate this, which defines how it will be enforced. Everything that is done in the name of security must be enforced. It is an excellent idea to employ both control system engineers and IT specialists to work together to maintain the network. If you are unable to employ individuals, you may outsource the positions. The team should schedule risk analysis on a regular basis, implement change control and monitor the network regularly. Additionally, create policies and procedures that describe and outline risk mitigation, alert vectors, and actions to be taken if any type of security breach is detected. Furthermore, your operating staff should know exactly who to contact in the case of a breach or attack on the security of the network.
