ETHOS is the Cisco file grouping engine. It allows us to group families of files together so if we see variants of

a malware, we mark the ETHOS hash as malicious and whole families of malware are instantly detected.

Cisco Workload Optimization Manager provides specific real-time actions that ensure workloads get the

resources they need when they need them, enabling continuous placement, resizing, and capacity decisions that can be automated, driving continuous health in the environment. You can automate the software’s decisions according to your level of comfort: recommend (view only), manual (select and apply), or automated (executed in real time by software).

 GET VPN (Group Encrypted Transport VPN) is a tunnel-less VPN technology that uses a single security association (SA) for all routers in a group. This allows GET VPN to natively support MPLS and private IP networks, without requiring any additional encapsulation or tunneling protocols. GET VPN also supports multicast traffic without GRE, which reduces overhead and improves performance. FlexVPN is a newer VPN solution that covers all VPN types, such as site-to-site, hub and spoke, and remote access. FlexVPN uses IKEv2 for all VPN types, which offers some advantages over IKEv1, such as resiliency and fewer messages. However, FlexVPN requires newer hardware and software versions to support its features. FlexVPN also relies on GRE or static and dynamic point-to-point interfaces to support MPLS and private IP networks, which adds complexity and overhead. Therefore, a benefit of using GET VPN over FlexVPN within a VPN deployment is that GET VPN natively supports MPLS and private IP networks, without requiring any additional encapsulation or tunneling protocols. References:

Endpoint protection platforms (EPP) prevent endpoint security threats like known and unknown malware.

Endpoint detection and response (EDR) solutions can detect and respond to threats that your EPP and other security tools did not catch.

EDR and EPP have similar goals but are designed to fulfill different purposes. EPP is designed to provide

device-level protection by identifying malicious files, detecting potentially malicious activity, and providing tools for incident investigation and response.

The preventative nature of EPP complements proactive EDR. EPP acts as the first line of defense, filtering out attacks that can be detected by the organization’s deployed security solutions. EDR acts as a second layer of protection, enabling security analysts to perform threat hunting and identify more subtle threats to the endpoint.

Effective endpoint defense requires a solution that integrates the capabilities of both EDR and EPP to provide protection against cyber threats without overwhelming an organization’s security team.

The various suspicious patterns for which the Cisco Tetration platform looks in the current release are:

+ Shell code execution: Looks for the patterns used by shell code.

+ Privilege escalation: Watches for privilege changes from a lower privilege to a higher privilege in the process lineage tree.

+ Side channel attacks: Cisco Tetration platform watches for cache-timing attacks and page table fault bursts.

Using these, it can detect Meltdown, Spectre, and other cache-timing attacks.

+ Raw socket creation: Creation of a raw socket by a nonstandard process (for example, ping).

+ User login suspicious behavior: Cisco Tetration platform watches user login failures and user login

methods.

+ Interesting file access: Cisco Tetration platform can be armed to look at sensitive files.

+ File access from a different user: Cisco Tetration platform learns the normal behavior of which file is

accessed by which user.

+ Unseen command: Cisco Tetration platform learns the behavior and set of commands as well as the lineage of each command over time. Any new command or command with a different lineage triggers the interest of the Tetration Analytics platform.

Application visibility and control (AVC) is a solution that leverages multiple technologies to recognize, analyze, and control over 1000 applications, including voice and video, email, file sharing, gaming, peer-to-peer (P2P), and cloud-based applications1. One of the key components of AVC is application recognition, which uses stateful deep packet inspection (DPI) to identify applications within the network traffic flow, using L3 to L7 data2. DPI is a technique that examines the content of packets beyond the header information, and can classify applications based on their signatures, protocols, ports, or other attributes3. DPI enables AVC to monitor and control application performance, bandwidth usage, quality of service, and security policies4. References := 1: Cisco Application Visibility and Control (AVC) - Cisco 2: Cisco Application Visibility and Control User Guide - Technology Overview 3: What is application visibility and control? | Juniper Networks US 4: Application visibility and control - Secure Internet Access Enterprise

SSL decryption allows the intelligent proxy to inspect traffic over HTTPS. Some websites may use self-signed certificates or certificates that are not trusted by the user’s device. This may cause the browser to display a warning or an error message when accessing those websites through the intelligent proxy. To avoid this, the user’s device needs to trust the Umbrella root CA, which is the certificate authority that signs the certificates for the websites that are proxied by Umbrella. By importing the Umbrella root CA into the trusted root store on the user’s device, the browser will recognize the certificates as valid and will not alert the end-users12. References: 1: Enable SSL Decryption - Umbrella User Guide 2: Intelligent Proxy and SSL Decryption with Cisco Umbrella

DHCP option 82 is a feature that allows the network access device (NAD) to insert additional information into the DHCP request packet from the endpoint. This information can include the switch ID, port number, VLAN ID, and other attributes that can help Cisco ISE to identify and profile the endpoint. Cisco ISE can use DHCP option 82 to assign the endpoint to the appropriate identity group, policy, and authorization profile. DHCP option 82 is also useful to prevent rogue DHCP servers from assigning IP addresses to endpoints, as Cisco ISE can verify the legitimacy of the DHCP request based on the option 82 data. To use DHCP option 82, the NAD must be configured to enable this feature and send the option 82 data to Cisco ISE. Cisco ISE must also be configured to accept and parse the option 82 data from the NAD. For more details on how to configure DHCP option 82 on Cisco ISE and NAD, see the references below. References:

In XSS, an attacker will try to inject his malicious code (usually malicious links) into a database. When other users follow his links, their web browsers are redirected to websites where attackers can steal data from them. In a SQL Injection, an attacker will try to inject SQL code (via his browser) into forms, cookies, or HTTP headers that do not use data sanitizing or validation methods of GET/POST parameters.

To block a website based on a custom list, the customer should add the websites to a blocked type destination list. A destination list is a custom list of domains or URLs that the customer wants to allow or block for their identities. The customer can create destination lists through the Policy Components > Destination Lists page, or within the policy wizard when creating or editing a policy. The custom URL destination block lists feature enables Umbrella to extend a domain level block list to encompass full and partial URLs. In turn, this allows the customer to block certain portions of a website based specifically on the full or partial URL. This feature requires the customer to enable the intelligent proxy and install a root certificate for SSL decryption. References:

Explanation

Phishing is a form of social engineering. Phishing attacks use email or malicious web sites to solicit personal,

often financial, information. Attackers may send email seemingly from a reputable credit card company or

financial institution that requests account information, often suggesting that there is a problem.

Explanation

The logging of your identities’ activities is set per-policy when you first create a policy. By default, logging is on and set to log all requests an identity makes to reach destinations. At any time after you create a policy, you can change what level of identity activity Umbrella logs.

From the Policy wizard, log settings are:

Log All Requests—For full logging, whether for content, security or otherwise

Log Only Security Events—For security logging only, which gives your users more privacy—a good setting for people with the roaming client installed on personal devices

Don’t Log Any Requests—Disables all logging. If you select this option, most reporting for identities with this policy will not be helpful as nothing is logged to report on.
