The Role Of Vulnerabilities In Cisco Attacks

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

In order to mitigate these risks, it is imperative network switches are hardened. Additional controls may include ARP inspection, disabling unused ports and enforcing effective security on VLAN’s to prevent VLAN hopping.

In this report I will be describing the ways in which networks can be attacked, also be giving real life example of each of the below.

Security is almost certainly the most difficult aspect of a network to perfect. It is important to have the correct procedures and components in place to make certain network security is being accounted for and addressed on any given network. The journal, “Future Generation Computer Systems” elaborates on this necessity for an information system. “Future Generation Computer Systems”, this component of a network is discussed thoroughly. “Essentially securing an Information System (IS), involves identifying unique threats and challenges which need to be addressed by implementing the appropriate countermeasures” (Dimitrios Zissis, Dimitrios Lekkas, 2012). This was achieved through configuring access lists as well as CHAP configuration on the routers connecting to the edge

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.

Undoubtedly, this paper will generate network information, diagrams, and/or tables; accordingly, these are all included in the Appendix section of the paper. Moreover, the training, vulnerability assessment, and SAQ results are also included as an Appendix in the final paper. Finally, fearing disclosure of proprietary information that could compromise network security, all project data are scrubbed and sanitized to remove sensitive information.

The exponential increase use of the Internet to communicate, conduct business transactions, access personal banking, healthcare, education at confront of being anywhere has become an everyday lifestyle for many people around the globe. This reliance on computers, laptops, devices and other Internet of Things to access the Internet means, organizations, businesses and the government have also seen an increase occurrence of sophisticated attacks.

Internet and Web-based applications have made it possible to access information from anywhere. This new capability not only brings convenience to the authorized users but also motivates attackers alike. Only prevention based security measures that rely on access control or even fine-grained access control schemes, firewall and encryption, often fail to protect sensitive information against novel attacks. In view of this, a lot of emphasis is being given on strengthening intrusion detection systems for protecting secure information from unintended users.

These proposals and systems suggestions can minimize the vulnerabilities associated with any compromises or intrusions within the network. Deploying an intrusion detection system is an essential security strategy for monitoring a network information system for abnormal or authorized activity. An intrusion detection system (IDS) is set of tools which monitor a network topology by providing a system administrator with the overall picture of how the system is being utilized. Executing an IDS will make a difference in creating a defense in depth architecture to be more compelling in recognizing any form of malicious activities. The capacity of the IDS is to monitor and survey the network traffic without affecting network activity. IDS tools gather information and analyzes it against a pre-characterized manage set, and against a set of known assault 'marks'. The IDS can scan port numbers and to determine if any breaches or attacks are occurring (Kuipers,

By using the Colorado Energy Company diagram as their simulator project, allowed the students to analyze their systems for vulnerabilities, threats as well as risks. The network system was attacked due to possible malware, no firewall, network sniffing as well as spoofing. Having the above mentioned ways of securing the Colorado Energy Company’s network may not prevent an attack, but it definitely will make it more difficult for a potential attacker to gain access into their

Cyber-attacks are not unknown however attacks on critical infrastructure are increasing tremen-dously and impact of these are devastating if the systems attacked are Industrial Controlled Sys-tems (ICS). ICS comprises of industries such as oil, gas, water, electricity. An outage of these will result in the enormous loss not only financially but can endanger human life and destroy critical equipment, restoring which can be time-consuming and extremely tedious. Many organizations still rely on antiquated security systems making them vulnerable to the deadly attacks and it is high time to change. This research paper highlights the severity of critical infrastructure attacks and will focus on the strategies to mitigate the risk of these attacks by using techniques like Application whitelisting, patch management, holistic approach for ICS security and moving beyond software security and focusing on Hardware Enabled Trusted Crypto. It focusses on the management of critical infrastructure risks.

An attack is any malicious or accidental disruption in the confidentially, integrity, or availability of information and network resources. Attacks can come from many places, electronic, physical, or human. Electronics attacks may come from the external network (Internet) or the internal network (Intranet); physical attacks can come in the form of hardware and equipment sabotage or theft, and human attacks most often come in the form of social engineering. Some of the attacks identify and evaluate in this paper are: spoofing, replays attacks, access attack suppress-relay, and source and repudiation attack.

A recent shift in the market prompted Cisco to restructure its organization. This change introduced new vulnerabilities. Within this report is our recommendation to assist in the transition and a roadmap to ensure its success.

Doug Allred was Vice President of Customer Advocacy organization of the Cisco’s corporation. This organization was erected to consolidated all functions that directly touched the customer but sales to provide high-quality customer service. Since August 2001, the IT market turned down and brought severe challenges to Cisco as the company had to lay off 18% of its employees and reorganized its structure, transforming from decentralized organizational structure with three business units to centralized organization. However, these changes
