Essay about Technical Security Policy Proposal for Small Company

Despite the presence of network security devices such as firewalls and other security appliances, today's corporate networks are still vulnerable to both internal and external attacks by hackers intent on creating havoc. By proactively

1.1.4 Requirements for a firewall at each Internet connection and between any demilitarized zone (DMZ) and the internal network zone

6) How does the use of border, internal, and host firewalls provide defense in depth?

The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.

As part of the network security team, we will be proving IDI with a network security plan to mitigate the vulnerabilities that have been discovered. A secure site will be set up with network intrusion detection and network protection systems will be available to access via the internal network. Policies will be presented for remote access and the use of VPN. Also contained within this report will be strategies for hardening the network and mitigating risks. An updated network layout with increased network security to meet the current needs will be included.

Firewalls are set up on computers to help protect computers and other devices from attacks from potentially harmful websites and other resources. Proxies are servers that act as a middle man for computers. They allow users to make indirect connections to other servers. The LAN-to-WAN domain is where the infrastructure connects to the Internet. Updates, firewalls and proxies will help to keep things running and help to keep it protected.

The IPS and IDS systems will be another addition that will be used to protect the Riordan Manufacturing networks as well. There is a difference between these two systems and it is important to know what each one does. The IPS stand for Intrusion Prevention System. This system is designed to prevent attacks from hitting the network. For the new Riordan network the IPS system that will be implemented is Surefire because use a rule based detection engine known as Snort.

* The Intrusion Detection System (IDS) provides the network with a level of preventive security against any suspicious activity. The IDS achieves this objective through early warnings aimed at systems administrators. However, unlike IPS, it is not designed to block attacks.

The goal of intrusion detection is to monitor network assets, detect anomalous behavior, and identify misuse within a network (Ashoor, Gore, 2011). An intrusion detection system (IDS) is a device or software application that monitors network system activities for malicious activity or policy violations and produces reports to a management station (Kashyap, Agrawal, Pandey, Keshri, 2013), additionally there are three types of IDS:

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The means by which this control is accomplished varies widely, but in principle, the firewall is a pair of mechanisms, one that blocks traffic and one that permits traffic. Some firewalls emphasize blocking traffic, while others emphasize permitting traffic. The most important thing to recognize about a firewall is that it implements an access control policy. If you don't know what kind of access you want to permit or deny, or you let someone else or some product configure a firewall based on judgment other than yours, that entity is making policy for your whole organization.

Establishing an effective Information Technology Security Policy Framework is critical in the development of a comprehensive security program. The purpose of the Information Security Policy Framework is to insure your organization will be able to provide the minimum security level necessary to maintain confidentiality, integrity, and availability of the information it collects and uses.

Firewalls is categorized as a preventive control which is used as a defense shield around IT systems to keep intruders and hacking from occurring, whereas, an Intrusion Detection System (IDS) which is categorized as a detective control is used to detect intrusions that have already occurred (Cavusoglu, Mishra, & Raghunathan, 2005). However, IDSs are not

The reader will become familiarised with the term risk and it definitions from specifically the ISO 31000 standard of risk management and also the definition of risk from the criminology crime triangle. Which one of these two definitions that are the most suitable for usage within the security industry will be discussed and evaluated. How and why consequence is important when assessing risk priorities and determining where to allocate resources will be examined and answered.

There are various types of firewall both software and hardware. According to The National Institute of Standards and Technology (NIST) 800-10, firewalls is divided into three basic types, The Proxys firewall, Stateful Inspection firewall, and Packet Filtering firewall. The packet filtering firewall is the simplest type of firewall is a type of firewall which uses a list of firewall security rules which are able to restrict traffic based on Internet protocols, addresses and or port number. Utilizing this type of firewall management program web traffic allows for the flow of all web traffic to involve web base intrusion. In situations like this the user will need to also employ some form of intrusion prevention program along with their already established firewall security. This will help tell the difference between good and bad web traffic.

A threat agent is the facilitator of an attack however; a threat is a constant danger to an asset.
