- IT Security
What is Information Security?
Information Security deals with the systems and tools involved in protecting data from any kind of malicious activities such as modification, disruption, and destruction. Cryptographic tools are being designed and deployed to ensure the confidentiality, integrity, and availability of system data.
What is Context Information Security?
It is a method of improving the security strength by means of employing different types of context information. The end goal is to prevent unauthorized users from accessing the data. Hence information like device location, time, and device type are being gathered.
What are the Basic Principle of Information Security?
The CIA triad: Confidentiality, Integrity, and Availability are commonly called the principles of Information Security. While maintaining an Information system, it must be ensured that the information is accessed only by the legitimate people. Any information transmitted must be beyond the level of breach. As much as protecting the data during transmission, it is important to store data in a secure location where unauthenticated entities cannot access it.
What are IT Security Standards?
Information security standards are a set of regulations by which the existing procedures are evaluated. Any personnel/firm handling information should meet these minimum requirements. The benefits of meeting these standards include improved management, increased profits, enhanced reliability, and security of systems.
Why IT Security is Needed?
Because we don’t want our private data to be available for unknown persons. Our emails, social media posts, and banking information are not intended for public access. These kinds of information, when accessed by illegitimate hackers, can also be used for blackmailing, ransom, and threats. Hence it is important to implement information security procedures in order to prevent data theft and modification.
Why are Information & Privacy Security Necessary?
Maintaining private data is a basic right for every individual. Personal interests and desires should not be harmed in the process of information transmission. Theft of private data such as bank documents, license, and tickets can be used as a tool to exercise control over us. Data privacy is the link between the collection of data and the public expectation of privacy. This improves the safeguarding of personal data such as contact information, health, finance, and family.
How Important is IT Security?
Information Security is crucial to anybody dealing with computer information. Since the risk of data theft and modification is increasing at an alarming rate, it is more important than ever to secure your data. Technological giants rely on Information security to run their operations smoothly. Any breach of their security systems can hinder years of growth, operations, and cost the company a huge loss. Simultaneously, the private data of people such as credit card details, passwords, and preferences are also lost.
What are the Components of IT Security?
- Data Confidentiality- Safeguarding confidential data should be your highest priority when several users access your network.
- Data Integrity – Keeping up the accuracy and consistency of data over a long course of time is data integrity.
- Data Authenticity – Ensuring that the data remains original at the receiving end.
- Data Availability – Making data available to the right user at the right time.
Where can an Organization Place the IT Security Unit?
Information security in organizations should be kept under IT Security, administrative services, insurance &risk management, strategy &planning, legal, internal audit, help desk, accounting and finance, human resources, facilities management, and operations. However, the information security unit should not be placed with the information technology unit since they might both be at conflict with each other.
How can IT Security be achieved?
- Employing strong and two-factor authentication methods.
- Frequent security software updates.
- Enforcing cybersecurity policies among the employees.
- Safeguarding the company hardware.
- Data encryption and enabling BIOS passwords.
- Equipping all PCs and devices with anti-virus and anti-malware protection.
- Review firewall logs and change the settings often.
- Regular security audits and updating security policy.
What are the Objectives of IT Security
- Confidentiality – Prevents information from being accessed by unauthorized people.
- Integrity – Keeps information away from those who have no access to it to prevent data modification.
- Availability – Differentiating between system administrators and end users; granting access as per their roles.
- Non-repudiation – Binding contracts without any paper being printed for written signatures ensuring honesty among the involved parties.
What can be the Possible Consequences of IT Security breach
- Compromise your customer’s data
- Possible DDoS (Distributed Denial of Service) attack.
- Cost huge financial loss.
- Place trade secrets at risk.
- Virus and hackers attack.
- Long downtime.
- Brand reputation gets damaged.
- Hidden costs including legal fees.
- Online vandalism.
What are the Legal and Organizational Requirements for IT Security and Retention?
- By the Data Protection Act, private information must be kept safe to prevent a data breach.
- Confidential and sensitive information should be password-protected.
- Provide passwords separately from the file.
- A specific time limit has to be set for retaining any data.
How can Breaches of IT Security be Eliminated?
- Secure workstations and electronic gadgets.
- Employ strong encryption mechanisms for data transmission.
- Reduce the amount of sensitive data stored in the devices.
- Report any attempt of breach immediately to the authorities.
- Be careful not to put personal information in publicly accessible locations.
- Never use open/ unencrypted networks while sending data.
- Use strong and cryptic passwords difficult to crack.
- Set different passwords for different accounts.
- Install anti-malware software and update them frequently.
- Don’t grant access to unknown or suspicious programs on your computer.
- Destruct restricted data before the disposal of digital devices.
What are the Threats to IT Security?
- Here, list out the information security threats
- Virus – They hook themselves onto the program on a host computer.
- Trojans- They hide within legit software and steal information.
- Worms- Travel from one computer to another and consume hard disk space.
- Bots – Malicious worms that can infect the host.
- Adware – Monitor your preferences and display relevant ads.
- Spyware – Stay and register activities on your computer to reveal the information to interested parties.
- Ransomware – Lock your computer and ask for ransom in exchange.
- Rootkits – Gain root access or administrative privileges in the user system.
- Zombies – Monitors computer activities while waiting for hacker commands.
