Explanation

Symmetric encryption uses a single key that needs to be shared among the people who need to receive the message while asymmetric encryption uses a pair of public key and a private key to encrypt and decrypt messages when communicating.

Asymmetric encryption takes relatively more time than the symmetric encryption.

Diffie Hellman algorithm is an asymmetric algorithm used to establish a shared secret for a symmetric key

algorithm. Nowadays most of the people uses hybrid crypto system i.e, combination of symmetric and

asymmetric encryption. Asymmetric Encryption is used as a technique in key exchange mechanism to share secret key and after the key is shared between sender and receiver, the communication will take place using symmetric encryption. The shared secret key will be used to encrypt the communication.

Triple DES (3DES), a symmetric-key algorithm for the encryption of electronic data, is the successor of DES (Data Encryption Standard) and provides more secure encryption then DES.

Note: Although “requires secret keys” option in this question is a bit unclear but it can only be assigned to

Symmetric algorithm.

Web usage controls are a feature of Cisco Web Security Appliance (WSA) that allow administrators to define and enforce policies for web access based on URL categories. URL categories are groups of websites that share a common theme or content, such as news, sports, entertainment, etc. Cisco WSA uses the Cisco Dynamic Content Analysis Engine and the Talos Security Intelligence and Research Group to provide accurate and up-to-date URL categorization. Administrators can use the web usage controls to allow, block, warn, or monitor web requests based on the URL category of the destination website. They can also create custom URL categories to include or exclude specific domains or URLs from the predefined categories. Web usage controls help administrators to control web traffic, enhance security, improve productivity, and comply with regulatory and organizational requirements. References :=

Cisco Advanced Malware Protection (AMP) for endpoints can be seen as a replacement for the traditional antivirus solution. It is a next generation, cloud delivered endpoint protection platform (EPP), and advanced endpoint detection and response (EDR). Providing Protection – Detection Response

While Cisco Umbrella can enforce security at the DNS-, IP-, and HTTP/S-layer, this report does not require that blocking is enabled and only monitors your DNS activity. Any malicious domains requested and IPs resolved are indicators of compromise (IOC).
