Which tool is commonly used to scan a computer system for known malware signatures?
- Antivirus
- Browser
- Firewall
- VPN
Antivirus software is commonly used to scan a computer system for known malware signatures. It compares files and activities on the computer to a database of known malware signatures to detect and remove malicious software.
In the context of firewalls, what does the term "stateful inspection" refer to?
- A method for tracking network packets
- A process for encrypting data transmissions
- A technique for blocking network traffic
- A way to filter website content
"Stateful inspection" in firewalls refers to the method of tracking the state of active connections and making decisions based on the context of the traffic, enhancing security by understanding the state of network connections.
The principle that emphasizes using multiple layers of security measures to protect information and systems is called what?
- Defense-in-Depth
- Encryption
- Single Sign-On (SSO)
- Two-Factor Authentication
Defense-in-Depth is a security strategy that advocates implementing multiple layers of security measures. This approach helps to provide redundancy and ensure that even if one layer is breached, other layers can still protect the system. Single Sign-On, Two-Factor Authentication, and Encryption are important security concepts but not the same as Defense-in-Depth.
When an IDS generates an alert for an activity that isn't actually malicious, it's termed as a _______.
- False Negative
- False Positive
- True Negative
- True Positive
When an IDS generates an alert for non-malicious activity, it's called a 'False Positive,' indicating a potential security concern that is, in fact, benign.
When an attacker leaves a malware-infected USB drive in a public place hoping someone will find it and plug it into a computer, this technique is known as?
- Baiting
- Pharming
- Phishing
- Spoofing
This technique is called "baiting." It involves leaving a device (in this case, a malware-infected USB drive) in a location where someone may find it and plug it into a computer out of curiosity. Once connected, the malware can infect the victim's computer.
When performing ethical hacking, what permission level should the hacker ideally have?
- Limited Access
- No Permission
- Root/Administrator Access
- Standard User
Ethical hackers should ideally have Standard User permissions. Giving them full access could lead to unintended consequences, while having no access impedes their work. Standard User access provides a balance of access for testing without causing harm.
The GDPR regulation primarily pertains to the protection of personal data for citizens of which region?
- Australia
- Canada
- European Union
- United States
The GDPR (General Data Protection Regulation) primarily pertains to the protection of personal data for citizens of the European Union. It is a comprehensive data protection law that sets strict standards for how organizations handle personal data of EU residents, regardless of where the organization is based.
An organization is looking to secure its sensitive data transmissions over the internet. They decide to use a system where both the sender and the receiver have a set of keys, one public and one private. Which encryption system are they likely implementing?
- AES
- DES
- RSA
- SHA-256
They are likely implementing the RSA (Rivest-Shamir-Adleman) encryption system. RSA is a widely used public-key encryption system where each participant has a pair of keys: a public key for encryption and a private key for decryption. This ensures secure data transmission and is often used in secure communications and digital signatures.
Which encryption algorithm, once considered very secure, is now deemed vulnerable due to advances in computing power?
- AES
- DES (Data Encryption Standard)
- RSA
- SHA-1
DES (Data Encryption Standard) is an encryption algorithm that was once considered very secure but is now deemed vulnerable due to advances in computing power. It has been replaced by more secure algorithms like AES.
Which of the following is not typically a part of an effective incident response plan?
- Communication plan
- Data backup plan
- Incident classification and prioritization
- Security awareness training
Security awareness training is not typically a direct part of an incident response plan but rather a proactive measure to educate employees about security best practices. An incident response plan focuses on how to react to and mitigate security incidents after they occur.
