Explain briefly the five steps undertaken in risk analysis 5 Marks 2. a. Describe the procedure involved in automatic password cracking algorithm. 6 Marks b. Define the following terminologies: (i) Patent 1 Mark (ii) Trademark 1 Mark (iii) 1 Mark (iv) Trade Secret 1 Mark (v) Privacy 1 Mark c. One of the simplest ways to prevent attackers compromising the network is to customize the settings of the network. Customization of the network settings will give the network administrators an efficient means of monitoring network traffic. They can also put restrictions on the data, and the information exchanged over the network, to prevent exposure of the company’s network, thus preventing unknown, and unauthenticated, users from accessing the network. In this regard, describe the following components of network security: (i) Firewall 2 Marks (ii) Honeypot 2 Marks 3. a. Biometric measurements or personal attributes are used for authentication. These attributes are unique to the individual seeking to authenticate identification.

Physical security forms an essential pillar of an organization’s overall security architecture, safeguarding tangible assets such as personnel, facilities, hardware, and sensitive information stored physically. Four fundamental reasons highlight its necessity: firstly, to protect personnel from external threats or internal misconduct, ensuring a safe working environment; secondly, to safeguard organizational assets such as equipment, documents, and physical infrastructure from theft, vandalism, or sabotage; thirdly, to ensure the continuity of business operations by preventing physical disruptions; and fourthly, to comply with legal and regulatory requirements that mandate specific security standards for physical assets (Smith & Doe, 2020).

Asymmetric key encryption, also known as public-key cryptography, offers several benefits, including enhanced security through the use of two mathematically linked keys—one public and one private—allowing secure communication without sharing secret keys. Its advantages include the facilitation of digital signatures, authentication, and secure key exchange mechanisms (Barker & Schneier, 2019). However, it has limitations such as slower processing speeds compared to symmetric encryption, increased computational overhead, and potential vulnerabilities if private keys are compromised or not stored securely (Kumar et al., 2021).

The five steps in risk analysis involve identifying assets, assessing threats to those assets, evaluating vulnerabilities, analyzing the potential impact of threats exploitations, and determining appropriate mitigation strategies. This systematic process helps organizations understand their security posture and prioritize resources effectively (Allen, 2018).

Automatic password cracking algorithms follow procedures like collecting password hash data, using cracking tools such as brute-force, dictionary, or hybrid methods to guess passwords, and then comparing the guessed hashes against the stored hashes to find matches. These algorithms automate the process of discovering weak passwords or retrieving forgotten credentials, emphasizing the importance of strong, complex passwords for security (Morris, 2020).

Intellectual property and privacy rights are protected through specific legal terms: a patent grants exclusive rights to inventions; a trademark protects brand identifiers; trademarks are often associated with symbols, words, or logos that distinguish goods/services; trade secrets refer to confidential business information that provides a competitive advantage; privacy pertains to an individual's right to control personal information (Jones & Taylor, 2022).

Network security components like firewalls and honeypots serve crucial roles. A firewall acts as a barrier between trusted internal networks and untrusted external sources, filtering traffic based on predetermined security rules to prevent unauthorized access. Conversely, a honeypot is a decoy system intended to attract attackers, enabling monitoring of attack methods and gathering intelligence while protecting actual systems from compromise (Williams, 2019).

Biometric authentication leverages unique personal attributes for verifying identities. Four common biometric types include fingerprint recognition, facial recognition, iris scanning, and voice recognition. Errors in biometric systems are primarily two: false acceptance (allowing unauthorized users) and false rejection (denying authorized users), impacting system accuracy and security (Patel et al., 2020).

Pretty Good Privacy (PGP) is a widely adopted encryption program that provides secure email communication, data encryption, and digital signatures. Its purpose is to facilitate secure and private exchange of information over insecure channels (Zimmermann, 1995). PGP is used mainly for encrypting emails, verifying digital signatures to ensure authenticity, and encrypting files to protect sensitive data from unauthorized access (Hengartner & Pfitzmann, 2001).
