Trusted Automated eXchange of Intelligence Information (TAXII) is a collection of services and message exchanges that enable the sharing of cyber threat intelligence across product, service, and organizational boundaries. It is designed to support the exchange of CTI represented in STIX, but is not limited to STIX. TAXII defines an API that aligns with common sharing models, such as hub-and-spoke, peer-to-peer, and subscribe/publish. TAXII is not a public collection of threat intelligence feeds, a threat intelligence sharing organization, or a language used to represent security information. Those are possible descriptions of STIX, which is a complementary standard to TAXII. References: STIX and TAXII Approved as OASIS Standards to Enable Automated Exchange of Cyber Threat Intelligence, STIX V2.1 and TAXII V2.1 OASIS Standards are published, What is STIX/TAXII? | Cloudflare, What is STIX / TAXII?

 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:

 The dot1x system-auth-control command enables 802.1X globally on a Cisco switch. This command allows the switch to act as an authenticator for 802.1X clients connected to the switch ports. The switch will then communicate with a RADIUS server to authenticate the clients and grant or deny access to the network. The other commands are not related to enabling 802.1X globally. The dot1x pae authenticator command enables 802.1X authentication on a specific interface. The authentication port-control aut command enables automatic port-based authentication on an interface. The aaa new-model command enables the AAA framework for authentication, authorization, and accounting. References :=

Explanation

SSL Decryption is an important part of the Umbrella Intelligent Proxy. he feature allows the Intelligent Proxy to go beyond simply inspecting normal URLs and actually proxy and inspect traffic that’s sent over HTTPS. The SSL Decryption feature does require the root certificate be installed.

A passphrase is a type of protection that encrypts RSA keys when they are exported and imported. A passphrase is a sequence of characters that the user enters to decrypt the key. The passphrase acts as a symmetric key that is used to encrypt and decrypt the RSA key with a symmetric algorithm, such as AES. This way, the RSA key is protected from unauthorized access or tampering when it is transferred or stored. A passphrase can also provide additional security by adding entropy to the RSA key generation process. A file, NGE, and nonexportable are not types of protection that encrypt RSA keys when they are exported and imported. A file is a container that stores the RSA key, but does not encrypt it. NGE stands for Next Generation Encryption, which is a set of cryptographic standards and algorithms that Cisco recommends, but it is not a specific type of protection. Nonexportable is a property that prevents the RSA key from being exported at all, but it does not encrypt it. References: RSA/Schannel Key BLOBs, Common Encryption Types, Protocols and Algorithms Explained, Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0 (Module 5: Implementing Secure Communications with VPNs, Lesson 5.1: Implementing Site-to-Site VPNs, Topic 5.1.2: Implementing Site-to-Site VPNs with Pre-Shared Keys)

A mobile device management (MDM) solution is a software tool that helps organizations manage, secure, and monitor mobile devices such as smartphones, tablets, and laptops. Some of the benefits of using an MDM solution are:

A. grants administrators a way to remotely wipe a lost or stolen device: This feature allows administrators to erase all the data and settings on a device that is lost or stolen, preventing unauthorized access to sensitive information. This can also help comply with data protection regulations and policies12

E. allows for centralized management of endpoint device applications and configurations: This feature enables administrators to control the applications and settings on the devices, such as enforcing security policies, installing or updating software, configuring network access, and restricting device features. This can help improve productivity, performance, and compliance of the devices13

Other benefits of using an MDM solution are:

B. provides simple and streamlined login experience for multiple applications and users: This feature allows users to access multiple applications and services with a single sign-on (SSO) or multi-factor authentication (MFA) mechanism, reducing the hassle of remembering and entering multiple credentials. This can also enhance security and user satisfaction4

C. native integration that helps secure applications across multiple cloud platforms or on-premises environments: This feature allows applications to leverage the native security features of the devices, such as encryption, biometric authentication, and device attestation. This can also help protect the applications from malware, tampering, and data breaches across different environments.

D. encrypts data that is stored on endpoints: This feature allows data to be encrypted at rest and in transit on the devices, preventing unauthorized access or interception of the data. This can also help comply with data protection regulations and policies.

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."

DNS Tunneling is a method of cyber attack that encodes the data of other programs or protocols in DNS

queries and responses. DNS tunneling often includes data payloads that can be added to an attacked DNS

server and used to control a remote server and applications.

The Talos IP and Domain Reputation Center is the world’s most comprehensive real-time threat detection network. It collects and analyzes data from millions of web requests, emails, malware samples, open-source data sets, endpoint intelligence, and network intrusions. It assigns a reputation score to IP addresses and domains based on their observed malicious activity and behavior. The reputation score can range from -10 (very malicious) to +10 (very benign). The reputation score can be used to block or allow traffic, or to trigger further inspection or analysis. The Talos IP and Domain Reputation Center allows you to track the reputation of IP addresses for email and web traffic, as well as to look up the category, volume, and history of any IP address or domain. You can also submit feedback or request a change of reputation for any IP address or domain. References

The Cloudlock Apps Firewall is a feature of Cisco Cloudlock, which is a cloud-native cloud access security broker (CASB) that helps organizations move to the cloud safely. The Cloudlock Apps Firewall mitigates security concerns from an application perspective by discovering and controlling cloud apps that are connected to a company’s corporate environment, such as Google G Suite or Microsoft Azure Active Directory (AD). These cloud apps are authorized through OAuth to access corporate data and resources via APIs, and may pose risks such as data exfiltration, account compromise, or malicious behavior. The Cloudlock Apps Firewall provides visibility into the app ecosystem, including the app name, category, risk level, access scopes, and number of users. It also allows administrators to ban or allowlist apps based on their risk profile and compliance requirements. Additionally, the Cloudlock Apps Firewall leverages a crowd-sourced Community Trust Rating for each app, which reflects the feedback from other Cloudlock customers on the app’s security and functionality. References :=

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 :=

Explanation

Cisco Tetration platform studies the behavior of the various processes and applications in the workload,

measuring them against known bad behavior sequences. It also factors in the process hashes it collects. By

studying various sets of malwares, the Tetration Analytics engineering team deconstructed it back into its basic

building blocks. Therefore, the platform understands clear and crisp definitions of these building blocks and

watches for them.

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.

URL conditions in access control rules allow you to limit the websites that users on your network can access. This feature is called URL filtering. There are two ways you can use access control to specify URLs you want to block (or, conversely, allow):

– With any license, you can manually specify individual URLs, groups of URLs, and URL lists and feeds to achieve granular, custom control over web traffic.

– With a URL Filtering license, you can also control access to websites based on the URL’s general

classification, or category, and risk level, or reputation. The system displays this category and reputation data in connection logs, intrusion events, and application details.

Using category and reputation data also simplifies policy creation and administration. It grants you assurance that the system will control web traffic as expected. Finally, because Cisco’s threat intelligence is continually updated with new URLs, as well as new categories and risks for existing URLs, you can ensure that the system uses up-to-date information to filter requested URLs. Malicious sites that represent security threats such as malware, spam, botnets, and phishing may appear and disappear faster than you can update and deploy new policies.
