Mitigating external cyber-attacks
William Dilly
Keller University SEC572

External cyber-attacks are on the rise and have become a real challenge for network administrators as well as network design planners to ensure their respective networks are protected from external attacks resulting in loss of website availability, confidential data, and internal processes critical to mission objectives. Cyber-attacks can cost companies large sums of unrecoverable revenue associated with site downtime and possible compromise of sensitive confidential data. It is imperative today’s corporate network is configured and prepared to protect itself from external cyber-attacks. Since there is no 100% method to stop external cyber-attacks, attention to detail must be made in regards to proper configuration of the network to include state of the art hardware and software. To include current security patches for both software and hardware respectively. Additionally, hardware and software measures will be limited in their effectiveness without network policies and techniques to protect against external cyber-attacks such as Denial of Service, Distributed Denial of Service, Masquerading and IP Spoofing, Smurf Attacks, Land c Attacks, and Man-in-the-Middle attacks. In close coordination with our IS team engineers and IT network director an approved plan has been incorporated to minimize risk of an effective cyber-attack on our network. Specifically this plan covers a comprehensive review of current network design and interdependencies, Standard Operating Procedures, Emergency Operating Procedures, detailed analysis of every program, service, host, router, switch to include interaction between these services and resources.

Testing current system and policies by a certified third party security consultant on a not to interfere basis will provide invaluable insight on our network. Additionally, weekly

    To properly secure an information system means protecting its files and other confidential information from misuse. The current speed of technological growth requires ever evolving security measures to follow these developments. As the members of Team “A” set out to address this need, it was necessary to discuss the requirements. The foundation of all concrete security plans require a detailed knowledge of all current systems, the tools needed to accomplish security needs and employee training. The implementation of these requirements will be outlined within a final Security Presentation.…

    One of the most important first steps to risk management and implementing a security strategy is to identify all resources and hosts within the IT infrastructure. Once you identify the workstations and servers, you now must then find the threats and vulnerabilities found on these workstations and servers. Servers that support mission critical applications require security operations and management procedures to ensure C-I-A throughout. Servers that house customer privacy data or intellectual property require additional security controls to ensure the C-I-A of that data. This lab requires the students to identify threats and vulnerabilities found within the Workstation, LAN, and Systems/Applications Domains.…

    This guide is meant to describe best practices for the detection and prevention of denial of service attacks, such as the event that recently occurred at the university. It was determined that based on current security guidelines and current controls in place, the university was still severely vulnerable from an internal aspect and all identified gaps need to be addressed and resolved. Each control described below will provide a more in depth look at the overall strategy of how a network should be protected but still allow for the functionality that is required to maintain normal operations.…

    Defense in Depth provides the university several layers of protection. Starting at the endpoints, host intrusion protection (HIPS), should be installed on each Device. Properly installed, HIPS will not permit the installation of unauthorized programs. This was the root cause of the (D)DoS recently experienced. At the routers access control lists (ACLs) must be put in place to allow only traffic with a legitimate protocol and destination. Between the routers and the endpoint a firewall solution must be put in place. The firewall must be configured to allow only allowed protocols and port numbers to communicate with specific destinations. Between the firewall and endpoint a (D)DoS a detection tool (such as Arbor’s Prevail) must be put in place. This measure not only allows for quick detection of (D)DoS it also permits the automatic mitigation of the…

    Denial-of-service DoS attacks DoS attack is simply to send more traffic to a network address than the programmers who planned its data buffers anticipated someone might send. The attacker may be aware that the target system has a weakness that can be exploited or the attacker may simply try the attack in case it might work. According to AppliCure Technologies preventing Denial of Service Attack With dotDefender web application firewall you can avoid DoS attacks because dotDefender inspects your HTTP traffic and checks their packets against rules such as to allow or deny protocols, ports, or IP addresses to stop web applications from being exploited…

    Network: The network should be designed with security in mind. Its structure must support the company’s policies, relevant laws and regulations, without impairing the organization’s ability to conduct business. The network should be logically and physically separated into distinct and manageable security zones. Traffic between the security zones must be inspected and filtered, to ensure that only authorized network use is permitted, and all access is recorded for future auditing. Multiple devices and methods should be used to ensure security across all parts of the network. In preparing this recommendation, network security design principles have been drawn from the Cisco SAFE Reference Guide [33] and the Council on CyberSecurity’s Critical Security Controls for Effective Cyber Defense Version 5.1 [34].…

    Safety of data and information is a real important aspect of a company. Before we can create an outline for general security solutions we must first define what is needed. I recommend that we use a multi-layered security plan. There are a total of seven domains of an IT infrastructure including user domain, workstation domain, LAN domain, LAN-to-WAN domain, WAN domain, remote access domain, and system/application domain.…

    Hardware can be used to protect the network from outside threats. Intrusion detection systems (IDS) automate detection of threats and attack through traffic analysis. Cisco’s IDS “delivers a comprehensive, pervasive security solution for combating unauthorized intrusions, malicious Internet worms, along with bandwidth and e-Business application attacks” (Cisco Systems, 2007, Cisco Intrusion Detection). They take this one-step further with an intrusion prevention systems (IPS). IPS shifts the focus on the attacker, not the attack itself, by increasing the accuracy of threat prevention through global threat analysis (Cisco Systems, 2012, Intrusion Prevention System with Global Correlation). The Cisco Adaptive Security Appliances (ASA) “combines the industry 's most deployed stateful inspection firewall with…

    When it comes to risk management, risk mitigating controls are the key to reducing threats to the network infrastructure. These mitigating controls can be found within standards, such as ISO/IEC 27001, and suggest measures to take in order to reduce risk to an organization’s assets. It is important to understand what each of these controls are in regards to risk management as well as the types of assessments used in determining the proper methods in protecting the infrastructure of any network.…

    Security is a fundamental aspect of any network infrastructure. The goal is to always have the most up to date programs and protocols to ensure the protection of the network. No aspect is too small to over look. That could mean the difference between a secure network and a compromised network. The best way to achieve this is to break down every level and approach each one as a separate entity and secure it. Then you can modify it to suit the needs of your network.…
