 The Cisco Umbrella roaming client is a cloud-delivered security service for Cisco’s next-generation firewall that protects employees when they are off the VPN. No additional agents are required. Simply enable the Umbrella functionality in the Cisco AnyConnect client. One of the advantages of the Umbrella roaming client is that it provides visibility into IP-based threats by tunneling suspicious IP connections to the Umbrella cloud for inspection and blocking. This way, the roaming client can prevent malware, phishing, and command-and-control callbacks from reaching malicious domains and IPs, regardless of the port or protocol. The Umbrella roaming client also provides DNS-layer security when the VPN is off, and proactive blocking of emerging threats using real-time data analysis. References:

CoA (Change of Authorization) is a feature that allows ISE to dynamically change the authorization attributes of an endpoint after it has been authenticated. CoA can be triggered by various events, such as posture assessment, profiling, or manual intervention1. There are different types of CoA that ISE can send to the network access device (NAD) to perform different actions on the endpoint session. The CoA type that achieves the goal of forcing an endpoint to re-authenticate without disrupting its session is CoA Reauth. CoA Reauth instructs the NAD to initiate a new RADIUS authentication for the endpoint, which allows ISE to apply a new or updated policy based on the latest attributes of the endpoint2. The other CoA types do not achieve this goal, as they either disconnect the endpoint session or do not change the authorization attributes. Port Bounce causes the NAD to shut down and bring up the port where the endpoint is connected, which effectively disconnects and reconnects the endpoint session2. CoA Terminate causes the NAD to terminate the endpoint session and send an Accounting-Stop message to ISE2. CoA Session Query causes the NAD to send an Accounting-Request message to ISE with the current session information, but does not change the authorization attributes of the endpoint2. References:

Explanation

"configure INTRUSION RULES for DNP3" -> Documentation states, that enabling INTRUSION RULES is mandatory for CIP to work + required preprocessors (in Network Access Policy - NAP) will be enabled automatically:

"If you want the CIP preprocessor rules listed in the following table to generate events, you MUST enable them. See Setting Intrusion Rule States for information on enabling rules."

"If the Modbus, DNP3, or CIP preprocessor is disabled, and you enable and deploy an intrusion rule that requires one of these preprocessors, the system automatically uses the required preprocessor, with its current settings, although the preprocessor remains disabled in the web interface for the corresponding network analysis policy."

Explanation

There are two possible methods to accomplish the redirection of traffic to Cisco WSA: transparent proxy mode and explicit proxy mode.

In a transparent proxy deployment, a WCCP v2-capable network device redirects all TCP traffic with a

destination of port 80 or 443 to Cisco WSA, without any configuration on the client. The transparent proxy

deployment is used in this design, and the Cisco ASA firewall is used to redirect traffic to the appliance because all of the outbound web traffic passes through the device and is generally managed by the same operations staff who manage Cisco WSA.

Explanation

Cross site scripting (also known as XSS) occurs when a web application gathers malicious data from a user. The data is usually gathered in the form of a hyperlink which contains malicious content within it. The user will most likely click on this link from another website, instant message, or simply just reading a web board or email message.

Usually the attacker will encode the malicious portion of the link to the site in HEX (or other encoding methods) so the request is less suspicious looking to the user when clicked on.

For example the code below is written in hex:

href=javascript:alert&#

x28'XSS')>Click Here

is equivalent to:

Click Here

Note: In the format “&#xhhhh“, hhhh is the code point in hexadecimal form.

Cisco Hybrid Email Security is a unique service offering that combines a cloud-based email security deployment

with an appliance-based email security deployment (on premises) to provide maximum choice and control for

your organization. The cloud-based infrastructure is typically used for inbound email cleansing, while the onpremises appliances provide granular control – protecting sensitive information with data loss

prevention (DLP) and encryption technologies.

 Mobile Device Management (MDM) is a solution that allows an organization to manage, monitor, and secure mobile devices such as smartphones, tablets, and laptops. MDM provides two main advantages to an organization with regards to device management:

Asset inventory management: MDM helps an organization keep track of all the mobile devices that are connected to its network, including their location, status, configuration, and usage. MDM also enables an organization to remotely wipe or lock devices that are lost, stolen, or compromised, preventing data loss and unauthorized access. Asset inventory management helps an organization optimize its resources, reduce costs, and comply with regulations12.

Allowed application management: MDM allows an organization to control what applications can be installed and run on the mobile devices, as well as how they can access and share data. MDM can also push updates and patches to the devices, ensuring that they are always running the latest and most secure versions of the applications. Allowed application management helps an organization enhance security, productivity, and performance of the mobile devices34.

Explanation

Malware means “malicious software”, is any software intentionally designed to cause damage to a computer, server, client, or computer network. The most popular types of malware includes viruses, ransomware and spyware. Virus Possibly the most common type of malware, viruses attach their malicious code to clean code and wait to be run.

Ransomware is malicious software that infects your computer and displays messages demanding a fee to be paid in order for your system to work again.

Spyware is spying software that can secretly record everything you enter, upload, download, and store on your computers or mobile devices. Spyware always tries to keep itself hidden.

An exploit is a code that takes advantage of a software vulnerability or security flaw.

Exploits and malware are two risks for endpoints that are not up to date. ARP spoofing and eavesdropping are attacks against the network while denial-of-service attack is based on the flooding of IP packets.

The process of performing automated static and dynamic analysis of files against preloaded behavioral indicators for threat analysis is called advanced sandboxing. Advanced sandboxing is a feature of Cisco Secure Malware Analytics (Threat Grid), which is a cloud-based or on-premises solution that analyzes the behavior of suspicious files and URLs. Advanced sandboxing uses a combination of static and dynamic analysis techniques to examine the files against more than 700 behavioral indicators, such as registry changes, network connections, file modifications, and process injections. These indicators help to uncover stealthy and sophisticated threats, and provide the security team with detailed reports and actionable intelligence. Advanced sandboxing also integrates with other Cisco security products, such as AMP, Firepower, and Email Security, to provide comprehensive malware protection across the network. Advanced sandboxing is different from other options, such as deep visibility scan, point-in-time checks, and advanced scanning, which are not specific processes or features of Cisco Secure Malware Analytics. Deep visibility scan is a generic term that refers to the ability to inspect network traffic and files for malicious activity. Point-in-time checks are periodic scans that detect malware at a specific moment, but do not provide continuous analysis or retrospective security. Advanced scanning is also a generic term that can refer to any scanning technique that goes beyond basic signature-based detection, such as heuristic analysis, machine learning, or behavioral analysis. References :=

 The Decrypt for Application Detection feature within the WSA Decryption options enhances the ability of AsyncOS to detect HTTPS applications. The HTTPS Proxy can decrypt HTTPS connections to web applications. This allows the Application Visibility and Control (AVC) engine to more accurately detect and block web applications that use HTTPS. This feature can help improve the security and performance of the network by identifying and controlling the usage of web applications that may consume bandwidth, pose security risks, or violate compliance policies.
