The process in DevSecOps where all changes in the central code repository are merged and synchronized is called Continuous Integration (CI). CI is a practice that aims to improve the quality and speed of software development by automating the building, testing, and integration of code changes. CI enables developers to collaborate more effectively and detect errors early in the development cycle. CI also helps to ensure that the code in the repository is always in a deployable state and conforms to the security and quality standards123. References: 1: Implementing and Operating Cisco Security Core Technologies (SCOR) course, Module 5: Secure Network Access, Identity Management, and Visibility, Lesson 5.1: Introducing DevSecOps 2: DevSecOps code process - AT&T4 3: Building a DevSecOps Culture - from a Technical Perspective5

Explanation

Unlike the traditional software life cycle, the CI/CD implementation process gives a weekly or daily update

instead of monthly or quarterly. The fun part is customers won’t even realize the update is in their applications,

as they happen on the fly.

Cross-site scripting (XSS) is a web security vulnerability that allows an attacker to inject malicious code into a web page that is viewed by other users. XSS can compromise the user’s interaction with the web application, steal sensitive data, perform unauthorized actions, and more. To prevent XSS, web developers need to apply various defensive techniques to ensure that user-supplied data is not interpreted as code by the browser. Two of these techniques are:

Incorporate contextual output encoding/escaping: This means that any user-supplied data that is displayed on the web page should be properly encoded or escaped according to the context where it appears. For example, if the data is inserted into an HTML attribute, it should be HTML attribute encoded; if the data is inserted into a JavaScript string, it should be JavaScript string encoded; and so on. This prevents the data from breaking out of its intended context and being executed as code by the browser. Output encoding should be done by using a reliable library or framework that supports different contexts and encodings.

Run untrusted HTML input through an HTML sanitization engine: This means that any user-supplied data that is intended to contain HTML markup should be filtered and validated by a sanitization engine that removes or escapes any potentially dangerous elements, attributes, or scripts. This prevents the attacker from injecting malicious HTML code that can execute scripts, load external resources, redirect the user, or perform other malicious actions. HTML sanitization should be done by using a well-tested and maintained library or framework that follows the best practices and standards for HTML filtering.

Explanation

This command uses RADIUS which combines authentication and authorization in one function (packet).

Explanation

Explanation

Telemetry – Information and/or data that provides awareness and visibility into what is occurring on the network

at any given time from networking devices, appliances, applications or servers in which the core function of the

device is not to generate security alerts designed to detect unwanted or malicious activity from computer

networks.

Explanation

In explicit proxy mode, users are configured to use a web proxy and the web traffic is sent directly to the Cisco WSA. In contrast, in transparent proxy mode the Cisco WSA intercepts user's web traffic redirected from other network devices, such as switches, routers, or firewalls.

Explanation

Explanation

Cisco IOS public key infrastructure (PKI) provides certificate management to support security protocols such as IP Security (IPSec), secure shell (SSH), and secure socket layer (SSL). This module identifies and describes concepts that are needed to understand, plan for, and implement a PKI.

A PKI is composed of the following entities: …

– A distribution mechanism (such as Lightweight Directory Access Protocol [LDAP] or HTTP) for certificate revocation lists (CRLs)

Explanation

The Version 1 format was the initially released version. Do not use the Version 1 format unless you are using a legacy collection system that requires it. Use Version 9 or Version 5 export format.

Version 5 export format is suitable only for the main cache; it cannot be expanded to support new features.

Version 8 export format is available only for aggregation caches; it cannot be expanded to support new

features.

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."

Dynamic ARP Inspection (DAI) is a security feature that validates ARP packets in a network. DAI allows a network administrator to intercept, log, and discard ARP packets with invalid MAC address to IP address bindings. This capability protects the network from certain “man-in-the-middle” attacks. DAI determines the validity of an ARP packet based on valid IP to MAC address bindings from the DHCP snooping binding database. DAI also supports static ARP ACLs for hosts with static IP addresses. DAI checks all ARP packets on untrusted interfaces, and only forwards the packets that have valid bindings. DAI can also rate-limit the ARP packets on untrusted interfaces to prevent DoS attacks. The other options are incorrect because:

B. In a typical network, DAI should be configured to make all ports as untrusted except for the ports connecting to trusted hosts or switches, which are trusted.

C. DAI does not associate a trust state with each switch, but with each interface on the switch.

D. DAI intercepts all ARP requests and responses on untrusted ports only, not on trusted ports. 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.

 Tetration is the solution that protects hybrid cloud deployment workloads with application visibility and segmentation. Tetration enables a zero-trust model using segmentation, which allows you to identify security incidents faster, contain lateral movement, and reduce your attack surface. Tetration supports both on-premises and public cloud workloads and provides real-time telemetry data, behavior analysis, software inventory, and policy enforcement. Tetration is part of the Cisco Zero Trust portfolio, which also includes solutions for securing the workforce and workplace. References:
