A PAC file is a Proxy Auto-Configuration file that contains a JavaScript function that determines whether web browser requests go directly to the destination or are forwarded to a web proxy server. A PAC file allows the client desktop browsers to be configured to select when to connect direct or when to use the proxy based on the URL and the host name. A PAC file can be downloaded from a web server or a local file. A PAC file is more suitable for complex proxy configurations or multiple proxy servers12

A transparent mode is a proxy configuration where the client browsers do not need to be configured to use the proxy. The proxy intercepts the traffic and forwards it to the destination. A transparent mode does not allow the client browsers to select when to connect direct or when to use the proxy34

A forward file is not a valid proxy configuration method.

A bridge mode is a network configuration where a device connects two or more network segments and forwards traffic between them. A bridge mode is not a proxy configuration method5 References := 1: Proxy Auto-Configuration (PAC) file - HTTP | MDN 2: Proxy auto-config - Wikipedia 3: Explicit and Transparent Proxy - techdocs.broadcom.com 4: Configure Explicit Proxy - Palo Alto Networks | TechDocs 5: config web-proxy explicit | FortiGate / FortiOS 7.4.0

Explanation

The AES encryption algorithm encrypts and decrypts data in blocks of 128 bits (block size). It can do this using 128-bit, 192-bit, or 256-bit keys

Explanation

Denial-of-service (DDoS) aims at shutting down a network or service, causing it to be inaccessible to its

intended users.

The Smurf attack is a DDoS attack in which large numbers of Internet Control Message Protocol (ICMP)

packets with the intended victim’s spoofed source IP are broadcast to a computer network using an IP

broadcast address.

The Cisco Stealthwatch system collects and analyzes network telemetry such as flow (NetFlow, sFlow, JFlow, IPFIX, etc.) from routers, switches, and firewalls to monitor network and user behavior. The system conducts sophisticated, proprietary analytics on network data to automatically detect abnormal behaviors that may signify an attack1. NetFlow is a protocol that provides information about network traffic flows, such as source and destination IP addresses, ports, protocols, bytes, packets, and timestamps. NetFlow data can be used to identify network anomalies, bandwidth usage, application performance, and security incidents2. References :=

 Cisco Duo is a cloud-based solution that provides multi-factor authentication (MFA) and device trust for secure access to applications and data. MFA adds an extra layer of security by requiring users to verify their identity with something they know (such as a password) and something they have (such as a phone or a hardware token). Device trust ensures that only trusted devices can access sensitive resources by checking the device health and compliance. Cisco Duo can help prevent social engineering attacks by making it harder for hackers to impersonate legitimate users or compromise their credentials. Cisco Duo can also integrate with other Cisco security products, such as Cisco AnyConnect, Cisco AMP for Endpoints, and Cisco Umbrella, to provide a comprehensive security solution. References :=

Explanation

A buffer overflow (or buffer overrun) occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program attempting to write the data to the buffer overwrites adjacent memory locations.

Buffer overflow is a vulnerability in low level codes of C and C++. An attacker can cause the program to crash, make data corrupt, steal some private information or run his/her own code. It basically means to access any buffer outside of it’s alloted memory space. This happens quite frequently in the case of arrays.
