What is Information security?
Information security is the set of strategies for preventing unauthorized access, disclosure, use, modification, inspection, recording or destruction of information regardless of the form the data may take like electronic or physical. Information security programs are built around the core objectives of the CIA Triad i.e. maintaining the confidentiality, integrity, and availability of IT systems and business data. These make sure that sensitive information is only disclosed to the authorized person, while maintaining a focus on efficient policy implementation and no obstruction to the growth of the organization.
IT security specialists are employed in many major enterprises due to the nature and value of the data within larger business. Their main job is to keep the data of the company secure from malicious cyber attacks that often attempt to breach into critical private information or gain control of the internal systems. The security measures deployed for information security are encryption key management, network intrusion detection systems, password policies, and regulatory compliance’s. A security audit will be conducted to audit to evaluate the organization’s ability to maintain secure systems against set of criteria.
A Threat is anything that can negatively alter, disrupt, hide, or erase information. Threats to sensitive information come in many different forms,
Weak Security: There are new technologies being released every day. This presents a very serious risk; each unsecured connection means that the data within the technology or data used by the technology is vulnerable to breaches.
Outdated security: Security software is a basic technology management practice and a mandatory step to protecting big data, when the software is not updated it becomes a mean for newer malicious code to go undetected and the data will be compromised.
Lack of Encryption: Protecting sensitive data in transit is a measure that few companies can embrace, despite its effectiveness. Encrypted data can only be accessed by an authorized person or with a unique ID, if the unencrypted data is stolen then it is easy for anyone to access it.
Social Media attacks: Social media is used as medium to distribute a complex geographical attack called eater holing. The attackers usually identify and attack a cluster if websites that they believe members of an organization will visit.
Mobile Malware: The mobile security is cause for concern since the early stages of their connectivity to the internet. It has become a key concern with the lack of security provided for these devices considering that almost every person on the world has a mobile device.
Lack of proper configuration: Big companies neglect the importance of properly configured security settings. Data breach is easily enabled as a result of several critical functionalities needed to fully protect the information of the organized is neglected.
Responses to threats
- Implementing safeguards and countermeasures to eliminate vulnerabilities or to block threats
- Assign another entity or organization to look after threats
- Plan for alternative supply chain models for critical systems and services.
- Using advanced analytics tools to eliminate threats
- Deploying cognitive security solutions
- Monitoring workload access and security policies in place and identifying deviations from security policies and indicators of possible compromise.
- Blocking suspicious apps, revoke unauthorized access and remotely wipe company data
- Identify breaches early through proactive notification of suspicious behavior
