Reconnaissance is the information-gathering stage of the cyber attack lifecycle. During this phase, attackers attempt to understand the target environment before selecting a delivery path or exploit. A host sweep is a reconnaissance activity because it identifies live systems within an address range. This helps an attacker map reachable hosts, discover exposed services, and prioritize later scanning or exploitation. File exfiltration occurs much later, during actions on objectives, after access has been obtained. SQL injection is an exploitation technique against an application or database-backed service. A phishing campaign is normally associated with delivery, where the attacker attempts to place a malicious link, attachment, or credential-harvesting page in front of a user. Reconnaissance is the attacker's ''survey the terrain'' phase: it does not yet require compromise, but it materially improves the attacker's chance of success.

DNS provides translation between human-readable domain names and IP addresses. For example, users remember domain names, while network communication requires IP addresses to route traffic. DNS resolves the name to the address needed for the connection. DNS does not provide local RIP tables; RIP is a routing protocol. It does not create IPsec tunnels; VPN technologies and protocols such as IKE and IPsec handle that. DNS also does not scan networks for vulnerabilities. From a security perspective, DNS is highly important because many attacks rely on domain names for phishing, malware delivery, command-and-control, or data exfiltration. DNS logs can help investigators identify suspicious lookups, newly registered domains, and connections to known malicious infrastructure. DNS security controls may block or sinkhole malicious domains before a connection is established. In simple terms, DNS is the phonebook of network communication, but it is also a valuable security telemetry source.

CI/CD improves the secure development pipeline by making software build, test, delivery, and deployment processes more automated, repeatable, and controlled. Continuous integration encourages developers to merge code frequently into a shared repository where automated tests and checks can run. Continuous delivery keeps software in a deployable state, while continuous deployment can automatically release changes that pass required tests. Security can be embedded into this pipeline through static analysis, dependency scanning, container image scanning, secrets detection, infrastructure-as-code checks, and policy gates. The goal is not merely faster software delivery, but safer and more reliable delivery. Network threat alert potential is a SOC concern, not the primary CI/CD outcome. API interaction optimization may occur in development, but it is too narrow. Storage quotas for code are repository management settings. Secure CI/CD reduces late-stage security surprises and helps organizations detect weaknesses earlier when they are cheaper and easier to fix.

East-west traffic is internal traffic moving between systems within the same environment or data center. Packets moving between virtual servers across a virtual switch are east-west because they remain inside the data center or virtualized environment. This traffic may never pass through a traditional perimeter firewall unless the architecture specifically routes it through inspection points. Internet-originated traffic to a public IP address is north-south because it enters the environment from outside. Traffic from a virtual desktop to a cloud-based proxy leaves toward an external or cloud service, making it north-south or external service traffic. Traffic from a cloud-based server to a virtual desktop crosses environment boundaries and is not the clearest east-west example. East-west visibility is critical because attackers who compromise one workload often attempt lateral movement to other internal systems. Segmentation, internal firewalls, workload security, and telemetry help control this risk. Reference/topics: Network Fundamentals 2.2, east-west and north-south traffic; Cloud Security 5.4, virtualization.

IP subnetting divides a larger IP network into smaller logical networks by changing the subnet mask or prefix length. Because each subnet has a defined address range, subnetting directly limits how many usable host addresses are available inside that segment. For example, a smaller subnet provides fewer assignable private IP addresses, which restricts the number of devices that can be placed in that network. NAT translates addresses between networks, but it does not itself define the size of the internal address pool. Static routing controls forwarding paths and does not limit how many devices can receive private IP addresses. VLANs segment Layer 2 broadcast domains, but the host count is ultimately determined by the IP subnet assigned to that VLAN. In secure network design, subnetting is often paired with VLANs and zones so that addressing, routing, and policy enforcement align cleanly.
