Information Security

It is describing the status of security at the time of the plan.

a firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on a rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e.g., the Internet) that is not assumed to be secure and trusted.

Yes, it is called 'Denial of service attack'. This is an accidental attack due to failure of bug's rapid spread.

This type of encryption uses a single shared secret key to encrypt and decrypt data.

It performs asymmetric encryption and decryption using the CAPI implementation of the advance encryption standard algorithm.

It provides a managed implementation of the advanced encryption standard symmetric algorithm.

It helps verify that data originates from a specific party by creating a digital signature that is unique to that party.

It provides a cryptography next generation implementation of the secure hash algorithm for 512 bit hash values.

It computes the SHA512 hash algorithm for the input data using the managed library.

PAP uses a simple two-way handshake: the authenticator sends a challenge, and the peer responds with the username and password in plaintext. PAP is not secure as it transmits credentials unencrypted and doesn't use hashing like CHAP does.

A rogue access point is an unauthorized AP installed on a network without the IT department's knowledge, creating a security vulnerability. It allows unauthorized users to bypass network security and gain access to internal resources. Rogue APs do not alleviate congestion (option A), they do not encrypt traffic (option C - encryption is a function of legitimate APs using WPA/WPA2), and they definitely do not enforce authentication (option D - they bypass security). The primary risk is the security hole they create.

A Denial of Service (DoS) attack overwhelms a server with fake requests, consuming resources and preventing legitimate users from accessing the service. The key symptom is a server operating slowly under a high volume of malicious requests. Reconnaissance (A) is information gathering, access attacks (B) involve unauthorized entry, while worms (D) and viruses (E) are self-replicating malware.

A worm is a self-replicating malware that propagates across networks without requiring user interaction or a host program. Unlike viruses (which attach to files), Trojan horses (which disguise themselves as legitimate software), or man-in-the-middle attacks (which intercept communications), worms actively exploit vulnerabilities to spread automatically across network connections, making them particularly dangerous for network propagation.
