Transparent traffic redirection using WCCP is a deployment mode for the Cisco WSA that allows it to intercept and proxy web requests from client applications without requiring any configuration on the clients. This mode increases the visibility and control of web traffic, while making the proxy function invisible to the users. To support this mode, the Cisco WSA must be configured to use the transparent proxy mode, which enables it to listen on ports 80 and 443 for HTTP and HTTPS traffic, respectively. The Cisco WSA must also be configured to use WCCP service IDs, which are numerical identifiers that specify the type and range of ports to be redirected. For example, service ID 0 (web-cache) redirects port 80, service ID 70 (https-cache) redirects port 443, and service ID 60 (ftp-native) redirects port 21 and a range of passive FTP ports. The Cisco WSA must also be configured to join a WCCP group, which is a set of WCCP routers or switches that cooperate to redirect traffic to the WSA. The WCCP group can be specified by a group list, which is an access list that defines the IP addresses of the WCCP routers or switches, or by a password, which is a shared secret that authenticates the WCCP communication. The WCCP group must also be configured on the network device that performs the traffic redirection, such as a Cisco router, switch, or ASA firewall. The network device must support WCCPv2, which is the latest version of the protocol that allows for advanced features such as load balancing, encryption, and GRE encapsulation. The network device must also be configured to use the same WCCP service IDs and group list or password as the Cisco WSA. The network device must also be configured to apply the WCCP redirection to the appropriate interface and direction, such as the inside interface and inbound direction for traffic originating from the internal network. The network device must also be configured to use an access list that defines the traffic to be redirected or bypassed, such as the source and destination IP addresses, ports, and protocols. The access list can also be used to exclude certain traffic from WCCP redirection, such as traffic to private or internal destinations, or traffic from specific hosts123 References := 1: Configure Transparent Redirection With WCCP in Order to Redirect Native FTP Traffic - Cisco 2: Solved: Transparent Redirection - Cisco Community 3: Cisco WSA : Is it possible to use web proxy in transparent mode without WCCP - Cisco Community

If sysopt permit-vpn is not enabled then an access control policy must be created to allow the VPN traffic through the FTD device. If sysopt permit-vpn is enabled skip creating an access control policy.

Stateful failover means that the connection state information is replicated from the active ASA to the standby ASA, so that in the event of a failover, the connections are preserved and do not need to be reestablished. Stateless failover means that the connection state information is not replicated, so that in the event of a failover, the connections are dropped and need to be reestablished by the end hosts. Stateful failover provides a smoother transition and less disruption to the network traffic, while stateless failover is simpler and less resource-intensive. References:

Platform as a Service (PaaS) gives the customer control of the deployed applications and their data while the provider manages the underlying platform, including compute, storage, networking, virtualization, operating system, runtime, and middleware. This division lets the company modify and patch its own application code without carrying the operational burden of the lower infrastructure layers. In IaaS, the customer must also administer the guest operating system, middleware, and runtime, which violates the requirement that the provider manage everything except the applications. SaaS provides a complete provider-managed application and therefore does not permit the required application-level control. “Hybrid cloud” describes a deployment architecture combining environments, not a service-responsibility model. PaaS is therefore the correct balance of application control and reduced operational responsibility. Cisco PaaS architecture guidance

Intra-EPG Isolation is an option to prevent physical or virtual endpoint devices that are in the same base EPG or microsegmented (uSeg) EPG from communicating with each other. By default, endpoint devices included in the same EPG are allowed to communicate with one another.

Explanation

The Firepower System uses network discovery and identity policies to collect host, application, and user data

for traffic on your network. You can use certain types of discovery and identity data to build a comprehensive

map of your network assets, perform forensic analysis, behavioral profiling, access control, and mitigate and

respond to the vulnerabilities and exploits to which your organization is susceptible.

You can configure your network discovery policy to perform host and application detection.

Using an Internet browser to access cloud-based service creates the risk of insecure implementation of API. API stands for Application Programming Interface, which is a set of rules and protocols that allow different applications or services to communicate and exchange data. API is often used to access cloud-based service, such as software as a service (SaaS), platform as a service (PaaS), or infrastructure as a service (IaaS). However, if the API is not implemented securely, it can expose sensitive data or allow unauthorized access to the cloud service. For example, an API may not use encryption, authentication, or authorization mechanisms to protect the data in transit or at rest. An API may also have vulnerabilities such as injection, broken authentication, or insufficient logging and monitoring, which can be exploited by attackers to compromise the cloud service or the user’s browser. Therefore, it is important to follow the best practices and standards for secure API development and testing, such as OWASP API Security Top 10. References:

 A SYN flood is a type of denial-of-service (DoS) attack that exploits the TCP three-way handshake process to exhaust the resources of a target server. The attacker sends a large number of SYN packets to the target server, each with a spoofed source IP address. The target server allocates resources for each incoming SYN packet and responds with a SYN-ACK packet to the spoofed address. However, the spoofed address never sends back the final ACK packet to complete the connection, leaving the target server with many half-open connections that eventually fill up its connection table. This prevents the target server from accepting new legitimate connections and causes service disruption123 References: 1: Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0 course overview 2: SYN Flood Explained. How to Prevent this Attack from Taking over your … 3: What is a SYN flood attack? | Cloudflare

According to the NIST 800-145 guide1, a community cloud is a cloud infrastructure that is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. A community cloud differs from a private cloud, which is provisioned for exclusive use by a single organization, and a public cloud, which is provisioned for open use by the general public. A hybrid cloud is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds). References := 1: NIST SP 800-145, The NIST Definition of Cloud Computing, page 3.

Cisco SensorBase gathers threat information from a variety of Cisco products and services, such as Cisco IPS, Cisco ASA, Cisco IronPort, Cisco Umbrella, and Cisco Talos, and performs analytics to find patterns on threats. This process is called consumption, which is one of the four phases of the Cisco Security Intelligence Operations (SIO) framework. The consumption phase involves collecting, aggregating, and analyzing threat data from multiple sources and providing actionable intelligence and tools to customers and partners. The consumption phase also leverages the Cisco SensorBase Network, which is the world’s largest threat monitoring network that tracks millions of domains and IP addresses around the world and maintains a global watch list for Internet traffic. SensorBase provides Cisco with an assessment of reliability for known Internet domains and IP addresses, based on their reputation score, category, volume, and threat level. SensorBase also provides threat data overviews, such as the top email and spam senders by country, and the standard categories used to classify website content and attack types1234. References := 1: How Cisco’s SensorBase works | Network World 2: What is Cisco SensorBase? - networklore.com 3: User Guide for AsyncOS 15.0 for Cisco Secure Web Appliance - GD … 4: Cisco Security Intelligence Operations At-A-Glance
