Intrusion Detection and Prevention Systems Simplified

Contributed by Arthur J. Wyatt
This paper attempts to cover and discuss several aspects of Intrusion Prevention Systems and Intrusion Detection Systems. This paper attempts to do this is simple and basic language. Both systems are explained and defined according to the National Institute of Standards and Technology. Following that several techniques that can be used to install or implement them are described. The techniques described are hubs, port mirroring, test access points, and inline. During the discussion of each there are figures to depict and assisting in conveying how each implementation works. How each works along with the security or performance issues is discussed. The last thing talked about in this paper network segmentation and how Intrusion Prevention Systems and Intrusion Detection Systems could be used in conjunction to layer security and enforce network use and security policies.

The Strengths and Limitations of DMZs in Network Security

Contributed by Cameron Meyer

A demilitarized zone (DMZ) in terms of a network is a segmented area in the network that is available to the public but is segmented in order to stay separated from a network’s internal private network. In other words, it separates the untrusted public Internet from the trusted network of an organization. This is done through the act of subnetting and is a useful network security design feature within the network architecture.

Security Concerns of Wearable Technology

Contributed by Mansur Abdulraheem

Wearable technology has grown extremely popular. From smartwatches to glasses, there are a variety of wearables that are now available to consumers for various purposes. Most consumers purchase these devices for ease of data access. Smartwatches may be used to avoid having to pull out their phone to collect basic information such as the weather forecast or to quickly read a text message or calendar reminder. Activity trackers help one improve on their workout and assist in tracking performance over time. Smart glasses allow us to better document our trips and experiences to help share with friends and family. So what happens to the data collected by wearables?

BGP Hijacking and Mitigation Techniques

Contributed by Christian Matlock

Due to the nature of how BGP operates and how it was designed, a series of both unintentional mistakes or malicious attacks could take place to take down an entire autonomous system; or a more nefarious act of intercepting traffic and then routing it to the correct destination could also take place. In order to combat the trusting nature of BGP, a series of threat mitigation techniques have been implemented in order to protect BGP against attacks. This includes setting up BGP neighbor authentications, filtering BGP prefixes with AS path access lists, BGP time to live (TTL) security check, and the future resource public key infrastructure (RPKI) have been put in use.
