DevSecOps takes the concept behind DevOps that developers and IT teams should work together closely, instead of separately, throughout software delivery and extends it to include security and integrate automated checks into the full CI/CD pipeline. The integration of the CI/CD pipeline takes care of the problem of security seeming like an outside force and instead allows developers to maintain their usual speed without compromising data security

 If an endpoint does not know how to reach its destination, it will send data to the specified default gateway. A default gateway is a device that routes traffic from a local network to other networks or the internet. The endpoint will use the default gateway’s IP address as the next hop for packets that are destined for unknown or remote networks. The default gateway will then forward the packets to the appropriate destination or another gateway, based on its routing table.  References :

Identity and access management (IAM) is a software service or framework that allows organizations to define user or group identities within software environments, then associate permissions with them. The identities and permissions are usually spelled out in a text file, which is referred to as an IAM policy.

A Jasager attack is a type of wireless man-in-the-middle attack that exploits the way mobile devices search for known wireless networks. A Jasager device will respond to any beacon request from a mobile device by saying “Yes, I’m here”, pretending to be one of the preferred networks. This way, the Jasager device can trick the mobile device into connecting to it, without the user’s knowledge or consent. The Jasager device can then intercept, modify, or redirect the traffic of the victim. For this attack to work, the attacker needs to be within close proximity of the victim, and the victim must have at least one known network in their preferred list. The victim does not need to manually choose the attacker’s access point, nor does the attacker try to get victims to connect at random.

Least privileges access control is the capability of a Zero Trust network security architecture that leverages the combination of application, user, and content identification to prevent unauthorized access. Least privileges access control means that users and devices are only granted the permissions they need to perform their tasks, and nothing more. This helps reduce the attack surface and makes it more difficult for attackers to gain access to sensitive data or resources. Least privileges access control is based on the principle of Zero Trust, which assumes that there are attackers both within and outside of the network, so no users or devices should be automatically trusted. Zero Trust verifies user identity and privileges as well as device identity and security, and requires end-to-end encryption. Least privileges access control also involves careful management of user permissions and network segmentation, which limit the amount of information and length of time people can access something, and contain the damage if someone does get unauthorized access.  References :  What Is Zero Trust Architecture? | Microsoft Security ,  Zero Trust security | What is a Zero Trust network? | Cloudflare ,  What is Zero Trust Architecture? | SANS Institute ,  What Is a Zero Trust Architecture? | Zscaler ,  What is Zero Trust Architecture (ZTA)? - CrowdStrike .

Selective network security virtualization: Intra-host communications and live migrations are architected at this phase. All intra-host communication paths are strictly controlled to ensure that traffic between VMs at different trust levels is intermediated either by an on-box, virtual security appliance or by an off-box, physical security appliance.

Cortex XDR is a detection and response platform that natively integrates network, endpoint, and cloud data to stop sophisticated attacks. A key benefit of Cortex XDR is that it acts as a safety net during an attack while patches are developed. Cortex XDR uses machine learning and behavioral analytics to detect and validate threats, and automatically reveals the root cause of alerts to speed up investigations. Cortex XDR also enables flexible and rapid response actions to contain and remediate threats across the environment.  References :  Cortex XDR- Extended Detection and Response - Palo Alto Networks ,  What is Cortex XDR | Palo Alto Networks ,  Cortex XDR Datasheet - Palo Alto Networks

Phishing is a type of attack that involves sending fraudulent emails that appear to be from legitimate sources, such as banks, companies, or individuals, in order to trick recipients into clicking on malicious links, opening malicious attachments, or providing sensitive information 1 2 .  The link to a malware website in the email is an example of a malicious link, which may lead to the installation of malware, ransomware, spyware, or other malicious software on the user’s device, or the redirection to a fake website that mimics a legitimate one, where the user may be asked to enter their credentials, personal information, or financial details 3 4 .  Phishing emails often use social engineering techniques, such as creating a sense of urgency, curiosity, or fear, to persuade the user to click on the link or attachment, or to reply to the email 5 .  Phishing emails may also spoof the sender’s address, domain, or logo, to make them look more authentic and trustworthy 6 .

Whaling, pharming, and spam are not the correct answers for this question.  Whaling is a specific type of phishing that targets high-profile individuals, such as executives, celebrities, or politicians, with the aim of stealing their confidential information or influencing their decisions 7 . Pharming is a type of attack that involves redirecting the user’s web browser to a fake website, even if they enter the correct URL, by modifying the DNS server or the user’s hosts file. Spam is the unsolicited or unwanted electronic messages, such as emails, texts, or instant messages, that are sent in bulk to a large number of recipients, usually for advertising, marketing, or scamming purposes.  References :

 Connectors and interfaces are the components that enable a SIEM to collect, process, and analyze data from various sources, such as Microsoft 365 services and applications 1 , cloud platforms, network devices, and security solutions. Connectors are responsible for extracting and transforming data from the source systems, while interfaces are responsible for sending and receiving data to and from the SIEM server. Without connectors and interfaces, a SIEM cannot operate correctly and ensure a translated flow from the system of interest to the SIEM data lake.  References :

Cortex XDR is a cloud-based, advanced endpoint protection solution that combines multiple methods of prevention against known and unknown malware, ransomware, and exploits. Cortex XDR uses behavioral threat protection, exploit prevention, and local analysis to stop the execution of malicious programs before an endpoint can be compromised. Cortex XDR also enables remediation on the endpoint following an alert or investigation, giving administrators the option to isolate, terminate, block, or quarantine malicious files or processes. Cortex XDR is part of the Cortex platform, which provides unified visibility and detection across the network, endpoint, and cloud.  References :
