What are the common threats for an information system?
Information security threats are a problem for many corporations and individuals. Viruses, worms, Trojans, and spam are ubiquitous, but they are just the tip of the iceberg. Other common information security threats include privilege escalation, spyware, adware, rootkits, botnets, and logic bombs.
What problems does a security risk assessment solve?
What problems does a security risk assessment solve?
- Identify assets (e.g., network, servers, applications, data centers, tools, etc.)
- Create risk profiles for each asset.
- Understand what data is stored, transmitted, and generated by these assets.
- Assess asset criticality regarding business operations.
What are two potential threats to applications?
Threats to applications can include the following: Unauthorized access to data centers, computer rooms, and wiring closets. Server downtime for maintenance purposes. Network operating system software vulnerability.
Which of the following is the most secure form of authentication?
The most secure form of the user authentication methods is a multi-factor or two-factor authentication process that understands the importance of the user experience (UX) and is external from the protected network, applications, and devices.
Is file shredding a security threat?
Many office paper shredders cut documents into vertical strips. The pieces of these documents can be easily reassembled, either manually or with readily available computer software programs, leaving businesses exposed to a potential data breach.
What is not a role of encryption?
What is not a role of encryption? Explanation: Encryption doesn’t have error correction or detection facility thus cannot be used to safeguard from data corruption.
Which of the following is an example of asymmetric encryption?
What Is the Difference Between Symmetric and Asymmetric Encryption?
| Differentiator | Symmetric Key Encryption | Asymmetric Key Encryption |
|---|---|---|
| Examples of Algorithms | Examples include RC4, AES, DES, 3DES, etc. | Examples include RSA, Diffie-Hellman, ECC, etc. |
What is difference between symmetric and asymmetric encryption?
The basic difference between symmetric and asymmetric key cryptography is that symmetric encryption requires the same key to be encrypted and decrypted. In the other hand, asymmetric encryption uses a key for encryption and uses another key for decryption.
What is asymmetric key system?
Asymmetric encryption, also known as public-key encryption, is a form of data encryption where the encryption key (also called the public key) and the corresponding decryption key (also called the private key) are different. Therefore, a recipient could distribute the public key widely.
Is AES symmetric or asymmetric?
AES is a symmetric algorithm which uses the same 128, 192, or 256 bit key for both encryption and decryption (the security of an AES system increases exponentially with key length).
