Firewalls, Intrusion Detection, Security

HCI security strategies focus on the External as well as Internal threats for each network system and its security requirements. Since networks and organizational needs vary from one company to another, one set of security rules does NOT fit all environments.

HCI can conduct a security and vulnerability assessment for your company and then propose and implement an optimized security solution to suit your organizational needs.

Firewalls

A firewall is a system designed to avert unauthorized access to or from a private network. Firewalls consist of a hardware device, software, or a combination of both. Firewalls are commonly used to prevent unauthorized Internet users from accessing private networks connected to the Internet. A firewall can also be used to log all attempts to enter the private network and prompt alarms when hostile or unauthorized entry is attempted.

Layered Security

Layered Security combines several different security components, such as anti-virus software, firewalls, and vulnerability assessment tools to create a comprehensive and defensive barrier. Layered security increases the difficulty of infiltration for an attacker and decreases the probability that they would bother pursuing your organization.

Intrusion Detection Systems

Intrusion Detection Systems (IDS) record any signs of unauthorized activity and access of your systems. IDS can cover both internal and external traffic and identify any unauthorized attempts to gain access to your company’s network. IDS can help you secure your company’s information. Threats are constantly increasing and can come from many different sources ranging from a disgruntled employee to a rival company to a foreign government. Weaknesses exist in systems and may be used to compromise your system. A critical intrusion could lead to down-time, theft of confidential information, or damaging public relations. IDS will help: 

                Detect an intruder
                Identify and stop the intruder
                Support investigations
                Reduce future intrusions

 Anti-Virus Software

 The Internet is an excellent means of communication, research, and business opportunities. However, the Internet, e-mail in particular, has created an avenue for the spread of computer viruses. Anti-virus software is designed to keep your computer free from viruses, worms, bots, etc. It scans your computer’s file system and looks for known viruses.

 Virtual Private Network

 A virtual private network (VPN) is a network that uses the public network to transfer information using secure methods. A message sent through a VPN travels through the Internet, but is encrypted so that the content remains private. The person who originated the document and the person who received the document are the only ones able to see the message in a readable state. Anyone trying to hack into the message would see only a scrambled mess.
