Term 815
The Service Trust Portal is a Microsoft website that gives IT professionals and auditors access to compliance documentation, audit reports, and security information about Microsoft cloud services.
Term 816
sFlow is a network monitoring technology that samples packets and exports traffic statistics to a central collector for analyzing network performance and security.
Term 817
SFP (Small Form-factor Pluggable) is a compact, hot-swappable transceiver that connects a network device to fiber optic or copper cabling for data transmission.
Term 818
SFP+ is an enhanced version of the Small Form-factor Pluggable transceiver that supports data rates up to 16 Gbps, commonly used for 10 Gigabit Ethernet and Fibre Channel connections in enterprise networking.
Term 819
SFTP (Secure File Transfer Protocol) is a network protocol that provides secure file transfer over SSH, encrypting both commands and data.
Term 820
SGID stands for Set Group ID, a Unix/Linux file permission that allows a process or executable to run with the group privileges of the file's group owner, not the user who runs it.
Term 821
Shared responsibility is a cloud security model where the cloud provider and the customer each own distinct parts of security and compliance duties.
Term 822
The shared responsibility model is a framework that defines which security and compliance tasks are handled by the cloud provider and which are handled by the customer.
Term 823
A shared secret is a piece of data, like a password or cryptographic key, known only to the parties involved in a secure communication, used to verify identity and protect information.
Term 824
A Shared VPC allows multiple projects or accounts within a cloud environment to use the same Virtual Private Cloud (VPC) network, enabling centralized management and isolation of resources.
Term 825
A shield in IT networking is a conductive layer around a cable or device that blocks electromagnetic interference to protect signal integrity.
Term 826
A Shielded VM is a Google Cloud virtual machine with enhanced security features that protect against rootkits and boot-level malware by verifying the integrity of the boot process and firmware.
Term 827
Shift left security is the practice of integrating security testing and controls earlier in the software development lifecycle, rather than waiting until after deployment.
Term 828
Shodan is a search engine that lets you find specific types of internet-connected devices, such as webcams, routers, and servers, by scanning the internet and indexing their services and banners.
Term 829
A social engineering attack where an attacker observes a victim's screen or keyboard to steal passwords or sensitive information.
Term 830
A side-channel attack is a type of security exploit that gathers information from a system by observing its physical or secondary outputs—such as timing, power consumption, or electromagnetic emissions—rather than directly attacking the software or cryptographic algorithm.
Term 831
SIEM (Security Information and Event Management) is a system that collects and analyzes log data from across an IT environment to detect and respond to security threats in real time.
Term 832
A SIEM query is a search command used in a Security Information and Event Management system to find, filter, and analyze security-related log data from across an organization's IT environment.
Term 833
SMTPS is a secure version of the Simple Mail Transfer Protocol that uses encryption to protect email messages during transmission between email servers.
Term 834
Single-mode fiber is a type of optical fiber used in high-speed, long-distance networking that transmits a single light signal along a very thin core, minimizing signal loss and enabling data to travel many kilometers without repeaters.
Term 835
A Service Level Agreement (SLA) is a contract between a service provider and a customer that defines the level of service expected, including metrics like uptime, response time, and penalties for non-compliance.
Term 836
SLE (Single Loss Expectancy) is the monetary loss expected each time a specific risk event occurs, calculated as asset value times exposure factor.
Term 837
An SLI (Service Level Indicator) is a carefully chosen metric that measures one specific aspect of a service's performance, such as request latency or error rate, to help determine whether the service is meeting its reliability goals.
Term 838
A Service Level Objective is a measurable target for a specific aspect of a service's performance or reliability that a team commits to meeting over a defined period.
Term 839
A Smart jack is a network interface device that regenerates, monitors, and troubleshoots digital signals between a service provider and customer equipment, often used with T1 or fiber lines.
Term 840
SMB is a network file-sharing protocol that allows applications to read, write, and request services from server programs in a computer network.
