Essay on What are Attack Trees?

Lately active defense in cyber security has been a very popular approach in protecting assets in cyberspace as well as mitigating the increase of cyber threats. Current defenses such as firewalls, antivirus, strong security policies and security patch updates aren’t sufficient enough to protect against the rapidly changing threat landscape. Many hackers can easily bypass traditional

It is not uncommon to find various organizations complaining about security flaws in their information systems. Failing to prevent or mitigate the security flaws may lead to system breakdown, errors, and loss of crucial information. This is why it is important for users of information systems to find the right solutions that can help counter and mitigate security flaws. One common problem with security flaws connected with information systems or networks is that the security flaws occur in multiples. Technological advances have, fortunately, made it possible for people and organizations to prevent and detect such security flaws using security strategies. Layered Security and Defense in Depth are two strategies that can help prevent attacks and protect information systems against security flaws. The two strategies are similar but are based on completely two different concepts. This paper compares and contrasts the Layered Security and Defense in Depth Strategies by explaining how each of the two functions. Additionally, the paper includes an explanation about the advantages and disadvantages of the two strategies.

Defense in depth identifies the need for many security layers to be utilised in defense of the system from the bottom as physical security to the top as Data security.

The threat kill chain reveals the stages of a cyber attack from early reconnaissance to the goal of information exfiltration. The kill chain can also be used as an organizational tool to help continuously improve network defense (Kill Chain). Threats must progress through seven stages of the model; the first stage is reconnaissance. Reconnaissance occurs when the attacker does a background check on the target before attacking them. Most reconnaissance is accomplished with the help of the Internet and social media accounts. The second stage is the weaponization phase. In this phase, the attacker creates a remote access

Due to the time restraint and the increasing focus on vulnerabilities in your security structure, this document only covers four of the areas that will eventually have written security policies.

Dougherty, C., Householder, A., & Houle, K. (2002). Computer attack trends challenge Internet security. Computer, 35(4), 0005-7.

Threat numbers for each scenario are determined by subject matter experts at an Intelligence Coordination Center (ICC) and provided through the MSRAM tool. It is important to note that users do not calculate threat probabilities. Instead, they use threat probabilities provided by the MSRAM tool. This is an

Incident response and planning is very critical to a business. It’s important Greiblock Credit Union (GCU) financial firm maintain control of these incidents in a timely manner which could reduce cost, and risks. When responding to incidents one should always minimize the severity of all security incidents. The analyst should have a clear plan to resolving incidents, while containing the damage and reducing risks (Cichonski et al., 2012). According to Cichonski et all, (2012) most departments have a Computer Security Incident Response team, or designated personnel to handle the variety of incident responses related to Cyber Security. Based on the below, the information can be used in a technique to help an organization to determine the threat against the organization and identify if it’s truly a security breach or serious

Further details about this topic will be discussed later in this research paper including the vulnerabilities attacks that are involved in Critical Infrastructure. Potential risk vulnerabilities that are used to make offense an attack are identified and risk and impact analysis on these potential risks to prevent from further attacks are also identified.

Create a model of defensive / defenses to counter both threats, including details of the response and how they stop every step of the attack model.

While analyzing the network for vulnerabilities, risks, threats and ways to secure the network, the below information are my findings.

"Something that has been mentioned indirectly a few times already is the concept of defense in depth. The concept of defense in depth originated from the military and was seen as a way to delay rather than prevent an attack. As an information security tactic, it is based on the concept of layering more than one control. These controls can be physical, administrative, or technical in design. We have looked at a variety of physical controls in this chapter such as locks, doors, fences, gates, and barriers. Administrative controls include policies

As information systems become progressively more complex, attackers also develop increasingly sophisticated attacks that threaten the integrity, confidentiality, and availability of these systems. Consequently, Information Technology (IT) security has become crucial to the survivability of the business. Companies may choose to employ safeguards to protect themselves from such threats, but what happens if these controls fail? Incident Response Plans (IRPs) are often employed as a means to mitigate and contain incidents when they occur, but their effectiveness is only as good as the planning that goes into their development. In response to this need, Intel has devised a strategy they refer to as Defense in Depth (DiDS).

The three practices of intelligence domain are attack models, security features, and standards and requirements. First, Attack models capture information used to think like an attacker: threat modeling, abuse case development and refinement, data classification, and technology-specific attack patterns (McGraw, 2004). Second, Security features and design practice is charged with creating usable security patterns for major security controls meeting the standards defined in the next practice, building middleware frameworks for those

As the technology is opening so many new methods for the attackers, we also need to utilize the same technology to implement counter methods to
