Which statement is true of symmetric cryptography? A. Symmetric cryptography is faster than asymmetric cryptography. B. Symmetric cryptography uses different keys to encrypt and decrypt messages. C. Symmetric cryptography does not require a secure mechanism to properly deliver keys. “The major strength of symmetric key cryptography is the great speed at which it can operate. Symmetric key encryption is very fast, often 1,000 to 10,000 times faster than asymmetric algorithms” (Chapple, Stewart, & Gibson, 2018, p. 216). 2. You have been specifically asked to implement a stream cipher. Which cryptographic algorithm could you use? A. RC4 B. RC5 C. RC6 “The Rivest Ciphers are a series of symmetric algorithms that include RC2, RC4, RC5, and RC6. RC4: A stream cipher (data is encrypted in real time) that uses a variable-length key (128 bits is standard)” (Miller & Gregory, 2016, p. 189). 3. Your organization is working with an international partner on a new and innovative product. All communication regarding this must be encrypted using a public domain symmetric algorithm. Which algorithm should you use? A. DES B. Blowfish C. 3DES IT 279 UNIT 4 ASSIGNMENT 2 “However, time trails have established Blowfish as a much faster algorithm than both IDEA and DES. Also, Mr. Schneier released Blowfish for public use with no license required. Blowfish encryption is built into a number of commercial software products and operating systems. A number of Blowfish libraries are also available for software developers” (Chapple, Stewart, & Gibson, 2018, p. 223). 4. You are the security administrator for an organization. Management decides that all communication on the network should be encrypted using the data encryption standard (DES) algorithm. Which statement is true of this algorithm? A. The effective key size of DES is 64 bits. B. A Triple DES (3DES) algorithm uses 48 rounds of computation. C. A DES algorithm uses 32 rounds of computation. IT 279 UNIT 4 ASSIGNMENT 5 C. Which of the following processes of risk management is the process of selecting strategies to deal with identified risk, according to business risk appetite? A. Risk assessment B. Establish scope and boundaries C. Risk treatment “Risk analysis identifies risks, quantifies the impact of threats, and aids in budgeting for security. It helps integrate the needs and objectives of the security policy with the organization’s business goals and intentions” (Stewart, Chapple, & Gibson, 2018, p. 83). D. Which of the following risk treatment options defines that a risk may be accepted? A. Mitigate the risk B. Transfer the risk C. Tolerate the risk “Accepting risk, risk tolerance, or acceptance of risk is the result after a cost/benefit analysis shows countermeasure costs would outweigh the possible costs of loss due to a risk” (Stewart, Chapple, & Gibson, 2018, p. 76).
