Information security, often abbreviated InfoSec, is a set
of security procedures and tools that broadly protect sensitive
enterprise information from misuse, unauthorized access,
disruption, or destruction. InfoSec encompasses physical and
environmental security, access control, and cybersecurity. It
often includes technologies like cloud access security brokers
(CASB), deception tools, endpoint detection and response
(EDR), and security testing for DevOps (DevSecOps), among
others.
Key elements of information security
InfoSec comprises a range of security tools, solutions,
and processes that keep enterprise information secure across
devices and locations, helping to protect against cyberattacks
or other disruptive events.
• Application security - Policies, procedures, tools, and best
practices enacted to protect applications and their data.w
• Cloud security - Policies, procedures, tools, and best
practices enacted to protect all aspects of the cloud,
including systems, data, applications, and infrastructure.
• Cryptography - An algorithm-based method of securing
communication meant to ensure only intended recipients
of a specific message can view and decipher it.
• Disaster recovery - A method to reestablish functional
technological systems in the wake of an event like a
natural disaster, cyberattack, or another disruptive event.
• Incident response - An organization’s plan for responding
to, remediating, and managing the aftermath of a
cyberattack, data breach, or another disruptive event.
• Infrastructure security - Security that encompasses
an organization’s entire technological infrastructure,
including both hardware and software systems.
• Vulnerability management - The process an organization
takes to identify, assess, and remediate vulnerabilities in
its endpoints, software, and systems.
Three pillars of information security: the CIA triad
Confidentiality, integrity, and availability make up the
cornerstones of strong information protection, creating the
basis for an enterprise’s security infrastructure. The CIA
triad offers these three concepts as guiding principles for
implementing an InfoSec plan.
Confidentiality
Privacy is a major component of InfoSec, and
organizations should enact measures that allow only
authorized users access to information. Data encryption,
multi-factor authentication, and data loss prevention are
some of the tools enterprises can employ to help ensure
data confidentiality.
Integrity
Enterprises must maintain data’s integrity across its
entire lifecycle. Enterprises with strong InfoSec will recognize
the importance of accurate, reliable data, and permit no
unauthorized user to access, alter, or otherwise interfere with
it. Tools like file permissions, identity management, and user
access controls help ensure data integrity.
Availability
InfoSec involves consistently maintaining physical
hardware and regularly completing system upgrades to
guarantee that authorized users have dependable, consistent
access to data as they need it.
