IT security professional can implement intrusion detection and auditing to monitor and notified of presentation layer attacks. Lastly, the application layer (Layer 7) supplies services to application procedures and threats are static passwords and SNMP private community strings (Holl, 2003). Organization will need to enforce encryption to limit the exposure of personal information, ensure that patches are installed for applications, patching and is performed on all network and hardware devices, hardening of operation system and implements secure authentication methods (Baker & Wallace, 2007). Additionally, a quality anti-virus is utilized on workstations, servers and other devices connected to the organization IT infrastructure. All types of attackers discussed in this paper are applicable.
The Internet presents various challenges in the realms of privacy and security. Such threats originate from obvious sources such as hackers and malware, but threats come from less obvious sources as well; employees, government agencies, and even one’s self through lack of knowledge or vigilance. Privacy, as explained by Lawrence Lessig (2006), “from the perspective of law, is the set of legal restrictions on the power of others to invade a protected space” (p.201). Cisco describes network security as the activities which protect a computer network to ensure “… the usability, reliability, integrity, and safety of your network and data” (n.d.). The two terms are closely related in Internet security, and as such, the threats outlined can be considered to have element of both privacy and security.
WIMAX Security Issues Threats to The WIMAX Some of the WIMAX threats are: Rogue base stations, DoS attacks, Man-in-the-middle attacks, and Network manipulation with spoofed management frames, Threats in the physical layer. Rogue base stations It is defined as an attacker, which copies a legitimate base station. It allows hackers to confuse subscribers. WiMAX uses time division multiple access, thus the rogue base station must transfer with a stronger power at the same time the legitimate station transfers. The authentication protocols (EAP Protocol) used in WiMAX help relieve this threat.
SSH addresses this issue by encrypting traffic sent between the devices. Even with these improvements in security, the original version of SSH, referred to as SSH1 or SSH-1, was not without its own vulnerabilities. One vulnerability of SSH-1 allowed an attacker to insert malicious commands into an encrypted session. These commands would be accepted by the server and ran with the privileges of the user that established the connection. This attack would become known as the “SSH insertion attack”.
How does cyber espionage affect Nation States/Organisation? The scope of this paper about Cyber Espionage will be explained in the three following areas: • How Nation States/Organisation target each other through cyber espionage? • How cyber espionage is implemented? • Strategies that can be utilized to reduce the effects of cyber espionage. What is cyber espionage?
Research Paper on Protecting Against Malware Among the three options given in the MIS6082 final paper requirements, i am going with option A and selecting Chapter 9 (Protecting Against Malware) as my research area. Research paper at a GLANCE 1. Introduction 2. Malware Categories of Malware Vulnerability to malware Symptoms of a malware affected system Famous malware attacks 3. Protecting against malware Anti Virus software Firewall Browser security Defensive Computing Other recommended methods INTRODUCTION In this globalized arena, with the proliferating computer users as well as computer networks, risks associated like Malware attacks are also multiplying.
I will also discuss a few steps to take to ensure online banking has appropriate security certificates for proper encryption purposes. As computers are mostly damaged and infected by means of worms and viruses, it is necessary to have a complete defense of the computer network or the computer itself. One of the first lines of defense of the machine is a firewall (Stankovic & Simic, 2009). Firewalls act as defenses and should be activated in order to prevent malicious attackers from entering into the system and networks (Vines, 2007). They are available in both physical and software forms.
In sybil attack, a attacker presents multiple addresses and behaves as if it were a group of nodes. There are, mainly, two different ways through which a sybil node can get an identity; stealing other node’s identity or fabricating fake identities. By impersonating a large number of nodes in the network, the attacker forbids other nodes from using those addresses, it can escape from detection systems. This attack can strongly harm geographic routing protocols, and can even threat multiple path routing schemes and node localization . B. Sinkhole attack A sinkhole attacker places itself at very strong status in the network and informs a high quality route to destination or spoofs neighboring nodes that are neighboring the destination.
In a DoS ... ... middle of paper ... ...ys during the process of exchanging keys of both hosts. Normally the data will be directly transmitted from your network to the network of your friend. However, due to the communication path being intercepted by the attacker, the data will now transfer to the attacker’s network first before transfer to your friend. As the public keys are still in the attack’s hand, the attacker can now decrypt the data sent by both of you, which results the data or the communication detail between you and your friend being stolen (Refer to Figure 2.2 in Appendix 2). In conclusion, the types of network attacks being focus in the report are denial of service attack, war dialing attack, and man-in-the-middle attack.
NIDS analyzes network packets on a network segment and either compare against known threats or analyze for patterns of malicious behaviour. A hybrid IDS combines these two methods (Endorf, Schultz and Mellander, 2004, p. 7). Two different analysis methods are used; rule-based detection analyses based on signatures, like virus scanning, and profile-based detection looks for abnormal data patterns (Endorf, Schultz and Mellander, 2004, pp. 16-17). Larger companies with sensitive information to protect should use hybrids to protect the network and those servers containing sensitive information.
