20+ practice questions focused on Network and Communications Security — one of the most tested topics on the Systems Security Certified Practitioner SSCP exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Network and Communications Security PracticeWhich protocol and port combination is commonly used for secure remote administration of a server?
Explanation: SSH operates on TCP port 22 and provides encrypted remote administration, while Telnet (port 23) is unencrypted. HTTPS (443) is for web traffic, and RDP (3389) is for remote desktop but not primarily for command-line administration.
A security analyst notices an unusual number of ARP replies on the network where one MAC address is claiming to be multiple IP addresses. Which type of attack is most likely occurring?
Explanation: ARP spoofing involves sending forged ARP replies to associate the attacker's MAC with the victim's IP, enabling man-in-the-middle attacks at Layer 2.
A company wants to deploy a firewall that can track the state of active connections and make decisions based on the context of traffic flows. Which firewall type should they choose?
Explanation: Stateful firewalls maintain a state table and track the state of connections, allowing them to make more intelligent filtering decisions compared to stateless packet filters.
During a wireless penetration test, an attacker captures the four-way handshake of a WPA2-PSK network and attempts to crack the passphrase offline. Which attack is the attacker likely using?
Explanation: The PMKID attack targets WPA2-PSK by capturing the PMKID from the RSN IE, which can be computed offline to brute-force the passphrase without requiring a full handshake.
Which protocol is used for secure web browsing and operates on TCP port 443?
Explanation: HTTPS (HTTP over TLS) uses TCP port 443 and provides encrypted communication for websites.
