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.

A cloud access security broker (CASB) is a security solution that helps protect cloud-hosted services and applications from cyberattacks and data breaches. A CASB acts as an intermediary between cloud users and cloud providers, and enforces the organization’s security policies and compliance requirements. A CASB integrates with other cloud solutions via APIs and monitors the cloud activity and data across multiple platforms and devices. A CASB can also create incidents based on events from the cloud solution, such as unauthorized access, data leakage, malware infection, or policy violation. A CASB can then alert the administrators, block the malicious actions, or remediate the issues. A CASB provides visibility, control, and protection for the organization’s cloud environment12.

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."

Multifactor authentication (MFA) is a security measure that requires two or more proofs of identity to grant access to network resources. These proofs can be something the user knows (such as a password or a PIN), something the user has (such as a token or a card), or something the user is (such as a fingerprint or a face scan). The benefit of using MFA is that it adds an extra layer of protection against unauthorized access, especially if the first factor (such as a password) is compromised or stolen. By requiring a second validation of identity, MFA reduces the risk of data breaches and identity theft. MFA can also help comply with regulatory and industry standards that mandate strong authentication for sensitive data and systems. References :=

hardware running a number of different Linux-based operating systems.

Explanation

In deceptive phishing, fraudsters impersonate a legitimate company in an attempt to steal people’s personal data or login credentials. Those emails frequently use threats and a sense of urgency to scare users into doing what the attackers want.

Spear phishing is carefully designed to get a single recipient to respond. Criminals select an individual target within an organization, using social media and other public information – and craft a fake email tailored for that person.

 To enable CWA for wireless guest access, the ISE engineer needs to configure the following steps on the ISE server:

Create a guest portal with the desired settings and appearance.

Create an authorization profile that references the guest portal and the DACL name for the Airespace ACL configured on the WLC. The DACL name must match the name of the ACL on the WLC exactly. The authorization profile also needs to have the common tasks of Web Redirection and Web Authentication enabled.

Create an authorization policy that matches the unauthenticated devices based on the MAC address or other criteria and applies the authorization profile created in the previous step.

The DACL name is required for the WLC to apply the correct ACL to the guest endpoints and redirect them to the guest portal. Without the DACL name, the WLC will not know which ACL to use and may grant full guest access to the endpoints. Therefore, the correct answer is D.

 IOS zone-based firewalls (ZBFW) are a feature that provides stateful firewall policies between groups of interfaces known as zones. A zone is a logical grouping of one or more interfaces that have similar security requirements. A zone can be applied to physical interfaces, subinterfaces, port channels, VLAN interfaces, or tunnel interfaces. However, an interface can be assigned only to one zone, and it cannot be shared between zones. This is because the ZBFW policy is applied between zones, not interfaces, and it controls the bidirectional traffic flow between them. Therefore, an interface can belong to only one zone at a time, and it must be removed from one zone before it can be added to another zone. This ensures that the firewall policy is consistent and unambiguous for each interface.

DNS tunneling is a technique that uses the DNS protocol to exfiltrate data or establish command and control channels between a compromised host and an attacker-controlled server. DNS tunneling can bypass network security controls that allow outbound DNS traffic without inspection or filtering. To stop DNS tunneling, two recommended approaches are:

Enforce security over port 53. This means applying firewall rules, access control lists, or other mechanisms to restrict outbound DNS traffic to only authorized DNS servers and domains. Additionally, DNS traffic should be inspected and analyzed for anomalies, such as unusually large or frequent queries, non-standard encoding, or suspicious domains. This can help detect and block DNS tunneling attempts.

Use Cisco Umbrella. Cisco Umbrella is a cloud-based security service that provides DNS security, web filtering, and threat intelligence. Cisco Umbrella can prevent DNS tunneling by blocking malicious domains, enforcing policies based on content categories, and applying machine learning to identify and stop emerging threats. Cisco Umbrella can also provide visibility and reporting on DNS activity and security events.

Explanation

Application layer protocols can represent the same data in a variety of ways. The Firepower System provides

application layer protocol decoders that normalize specific types of packet data into formats that the intrusion

rules engine can analyze. Normalizing application-layer protocol encodings allows the rules engine to effectively

apply the same content-related rules to packets whose data is represented differently and obtain meaningful

results.

To migrate a Cisco WSA virtual appliance from one physical host to another physical host by using VMware vMotion, both hosts must have access to the same defined network. This is because vMotion preserves the network identity and connections of the virtual machine, and requires that the source and destination hosts have compatible CPUs and shared storage1. The hosts do not need to run the same or different versions of Cisco AsyncOS, as long as they meet the minimum requirements for the virtual appliance2. The hosts do not need to use a different datastore than the virtual appliance, as vMotion can migrate virtual machines across datastores as well3. References: 1: VMware vMotion: Live Migration of Virtual Machines and Storage 2: Cisco Secure Web Appliance Virtual - Cisco 3: Migrating to Virtual SMA from Physical - Cisco Community

In a remote access VPN configuration, dynamic split tunneling allows traffic to certain trusted domains to bypass the VPN tunnel and exit through the client's local internet gateway. This feature selectively directs only the necessary traffic over the VPN, while allowing direct internet access for specific domains or traffic deemed safe or trusted, optimizing bandwidth and performance for remote users.

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.
