Security Operations (SecOps) is the process of coordinating and aligning security teams and IT teams to improve the security posture of an organization. SecOps involves implementing and maintaining security controls, technologies, policies, and procedures to protect the organization from cyber threats and incidents. When dealing with a known attack, SecOps must take the following action: document, monitor, and track the incident. This action is important because it helps SecOps to:

•Record the details of the attack, such as the source, target, impact, timeline, and response actions.

•Monitor the status and progress of the incident response and recovery efforts, as well as the ongoing threat activity and indicators of compromise.

•Track the performance and effectiveness of the security controls and technologies, as well as the lessons learned and improvement opportunities. References:

Short-range wireless:

● Adaptive Network Technology+ (ANT+): ANT+ is a proprietary multicast wireless sensor

network technology primarily used in personal wearables, such as sports and fitness sensors.

● Bluetooth/Bluetooth Low-Energy (BLE): Bluetooth is a low-power, short-range

communications technology primarily designed for point-to-point communications between wireless devices in a hub-and-spoke topology. BLE (also known as Bluetooth Smart or Bluetooth 4.0+) devices consume significantly less power than Bluetooth devices and can access the internet directly through 6LoWPAN connectivity.

● Internet Protocol version 6 (IPv6) over Low-Power Wireless Personal Area Networks

(6LoWPAN): 6LoWPAN allows IPv6 traffic to be carried over low-power wireless mesh

networks. 6LoWPAN is designed for nodes and applications that require wireless internet

connectivity at relatively low data rates in small form factors, such as smart light bulbs

and smart meters.

● Wi-Fi/802.11: The Institute of Electrical and Electronics Engineers (IEEE) defines the 802

LAN protocol standards. 802.11 is the set of standards used for Wi-Fi networks typically

operating in the 2.4GHz and 5GHz frequency bands. The most common implementations

today include:

‒ 802.11n (labeled Wi-Fi 4 by the Wi-Fi Alliance), which operates on both 2.4GHz and 5GHz

bands at ranges from 54Mbps to 600Mbps

‒ 802.11ac (Wi-Fi 5), which operates on the 5GHz band at ranges from 433Mbps to 3.46

Gbps

‒ 802.11ax (Wi-Fi 6), which operates on the 2.4GHz and 5GHz bands (and all bands between 1 and 6GHz, when they become available for 802.11 use) at ranges up to 11Gbps

● Z-Wave: Z-Wave is a low-energy wireless mesh network protocol primarily used for home

automation applications such as smart appliances, lighting control, security systems,

smart thermostats, windows and locks, and garage doors.

● Zigbee/802.14: Zigbee is a low-cost, low-power wireless mesh network protocol based on the IEEE 802.15.4 standard. Zigbee is the dominant protocol in the low-power networking market, with a large installed base in industrial environments and smart home products.

● Benign: Safe and does not exhibit malicious behavior

● Grayware: No security risk but might display obtrusive behavior (for example, adware,

spyware, and browser helper objects)

● Malware: Malicious in nature and intent and can pose a security threat (for example,

viruses, worms, trojans, root kits, botnets, and remote-access toolkits)

● Phishing: Malicious attempt to trick the recipient into revealing sensitive data

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.

SSL/TLS encrypts and authenticates web-based communication to ensure secure data transmission over networks. It ensures privacy by encrypting the data exchanged between a client and a server, protecting it from interception or tampering. It doesn’t handle user input like passwords directly.

A container-based NGFW is specifically designed to integrate with Kubernetes environments, providing full application visibility and control within containerized workloads. It operates at the pod level, making it ideal for securing dynamic microservices architectures.

Code security in cloud environments involves using tools like Static Application Security Testing (SAST) to automatically analyze source code for vulnerabilities before deployment. This helps identify and remediate potential threats early in the software development lifecycle.

HTTPS is a protocol that encrypts and secures the communication between web browsers and servers. HTTPS uses SSL or TLS certificates to establish a secure connection and prevent unauthorized access or tampering of data. HTTPS typically uses port 443, which is the default port for HTTPS connections. Port 443 is different from port 80, which is the default port for HTTP connections. HTTP is an unencrypted and insecure protocol that can expose sensitive information or allow malicious attacks. Port 443 is also different from port 5050, which is a common port for some applications or services, such as Yahoo Messenger or SIP. Port 5050 is not associated with HTTPS and does not provide any encryption or security. Port 443 is also different from port 25, which is the default port for SMTP, the protocol used for sending and receiving emails. Port 25 is not associated with HTTPS and does not encrypt the email content or headers. References:

Containers encapsulate applications and their dependencies into lightweight, portable units that can run consistently across multiple environments. This abstraction supports cloud-native development by enabling microservices architectures, rapid deployment, and scaling within orchestration platforms like Kubernetes. Containers accelerate cloud migration by decoupling applications from infrastructure, facilitating automation, and continuous integration/continuous deployment (CI/CD) workflows. Palo Alto Networks addresses container security by integrating runtime protection, vulnerability scanning, and compliance enforcement within its Prisma Cloud platform, ensuring safe adoption of cloud-native tools and methodologies.

Signature-based antivirus software is a type of security software that uses signatures to identify malware. Signatures are bits of code that are unique to a specific piece of malware. When signature-based antivirus software detects a piece of malware, it compares the signature to its database of known signatures12. If a match is found, the software can do three things to provide protection:

Alert system administrators: The software can notify the system administrators or the users about the malware detection, and provide information such as the name, type, location, and severity of the malware. This can help the administrators or the users to take appropriate actions to prevent further damage or infection3.

Quarantine the infected file: The software can isolate the infected file from the rest of the system, and prevent it from accessing or modifying any other files or processes. This can help to contain the malware and limit its impact on the system4.

Delete the infected file: The software can remove the infected file from the system, and prevent it from running or spreading. This can help to eliminate the malware and restore the system to a clean state4.
