BCS Updated CISMP-V9 Exam Questions and Answers by mali

In the context of information security vulnerabilities, we are typically referring to weaknesses that can be exploited by threats to compromise the confidentiality, integrity, or availability of an information system. Options A, B, and D all represent potential vulnerabilities:

• A: Use of HTTP for an Apache web server could allow for interception of data due to lack of encryption.
• B: An unpatched Windows operating system could have known security flaws that can be exploited.
• D: An unlocked filing cabinet could lead to unauthorized physical access to sensitive documents.

Option C, however, refers to the storage of confidential data in a fire safe, which is a protective measure rather than a vulnerability. A fire safe is designed to protect physical assets from damage or destruction, particularly in the event of a fire, and does not inherently contain a weakness that could be exploited by a cyber threat. Therefore, it is not considered an information security specific vulnerability.

References: The BCS Foundation Certificate in Information Security Management Principles provides a framework for understanding the various aspects of information security, including the identification and mitigation of vulnerabilities. The principles outlined in the certification materials emphasize the importance of protecting information assets from a wide range of threats, which includes securing both digital systems and physical data storage12345.

The primary reason organizations opt for outsourced managed security services is to gain access to specialized security tools and expertise that may not be feasible to maintain in-house due to cost or resource constraints. Managed Security Service Providers (MSSPs) offer a range of security services that can be tailored to an organization’s needs, allowing them to benefit from advanced security measures without the need for significant capital investment or the hiring of specialized staff. This shared service model is cost-effective and enables organizations to focus on their core business activities while ensuring robust security measures are in place. MSSPs can provide continuous monitoring, management of security devices and systems, incident response, and compliance support, which are crucial for maintaining a strong security posture in the face of evolving threats and complex regulatory environments.

References: The answer aligns with the knowledge provided by the BCS Foundation Certificate in Information Security Management Principles, which emphasizes the importance of cost-effective access to specialized tools and expertise through managed security services. Additionally, the benefits of MSSPs are supported by industry sources1234.

Changing default system passwords is a fundamental step in securing a new web server. Default passwords are often well-known and can be easily found in public documentation or through internet searches, making systems with unchanged default passwords highly vulnerable to unauthorized access. By changing these passwords, an administrator immediately reduces the risk of simple, automated attacks that exploit default credentials.

While the other options listed are also important security measures, they are not typically the first action taken. Encrypting the hard disk (B) is a good practice for protecting data at rest, but it does not protect against unauthorized access via default passwords. Hardening applications © and patching the OS (D) are critical for reducing the attack surface and protecting against known vulnerabilities, but they are generally performed after ensuring that the system is not accessible with default passwords.

References: The BCS Foundation Certificate in Information Security Management Principles emphasizes the importance of initial access control measures, such aschanging default passwords, as part of establishing a secure baseline before implementing further technical controls1.

RSA (Rivest-Shamir-Adleman) is a widely accepted asymmetric encryption algorithm. Unlike symmetric algorithms, which use the same key for both encryption and decryption, asymmetric algorithms use a pair of keys – a public key for encryption and a private key for decryption. This method allows for secure key exchange over an insecure channel without the need to share the private key. RSA operates on the principle that it is easy to multiply large prime numbers together to create a product, but it is hard to reverse the process, i.e., to factorize the product back into the original primes. This one-way function underpins the security of RSA.
