CRC Press, National Institute of Standards and Technology, U. No matter how big or small a company, having an effective IT Security System is crucial. IT Security is an umbrella term encompassing a set of strategies to prevent unwanted or unauthorised access to business or client computers, networks, and data.
The aim is to protect sensitive and important information from hackers — find out more about how hackers infiltrate security systems here. Large data breaches make the headlines occasionally, however breaches happen every hour of every day and should not be underestimated. Not only would infiltration of a network cost financially, but it also damages reputation. Some lower level hacks, such as phishing emails, can be prevented by educated persons, aware of the tell-tale signs.
Other hacks are more advanced, detected by software specially created to constantly scan and protect a network. This article will help you understand some of the most common IT Security strategies and why they are crucial for small or medium businesses, as well as the big players.
Network security encompasses both software and hardware implemented to target a variety of threats to stop them from entering or spreading on the network. Therefore, these strategies protect the usability and integrity of networks, ensuring data is guarded.
It is not interchangeable with IT Security as it deals specifically with data being sent through a network.
No matter how big or small a company is, if data is concerned, Network Security systems must be implemented. One way of protecting information is to ensure only authorised personnel have access to it.
Access Controls recognise each user and device, allowing and denying access accordingly. Vital to the affordance of Access Controls is that they guarantee a user is who they say they are; this helps protect against hackers claiming to be something they are not.
Malware takes many forms and easily infiltrates a network in the right conditions; therefore, Antivirus Software is put in place to scan for malware and rid it from a network.
Antivirus Software protects against viruses, worms, Trojans, ransomware, and spyware etc. Even if malware does make it through, effective Antivirus Software continuously scans to detect dormant malware to prevent future damage.
In order for a Network Security system to detect any abnormalities in the system, it has to know what is considered normal. Examples of E2EE in use include the WhatsApp messaging service , which famously asserts that users' messages are secured with "locks. Attackers will still attack even when they know that data or devices are encrypted. They figure that with some effort, they might get through. For many years, weak passwords served as the impetus for attackers to keep trying, as some sophisticated software could sooner or later figure out passwords.
Such brute force attacks have become more sophisticated, as attackers hope that by making thousands or even millions of guesses, they will figure out the key for decryption. However, most modern encryption methods, coupled with multi-factor authentication MFA , are helping organizations to become more resistant to brute force attacks. Encryption has become an enormous asset to organizations, allowing them to confidently offer a more secure experience for employees, customers, and other stakeholders.
Encryption can prevent data breaches. Even if an attacker maliciously gains access to a network, if a device is encrypted, the device will still be secure, rendering attempts by the attacker to consume the data useless. Encryption ensures no one can read communications or data except the intended recipient or data owner. This prevents attackers from intercepting and accessing sensitive data. Encrypting data allows organizations to protect data and maintain privacy in accordance with industry regulations and government policy.
Many industries, especially those in financial services and healthcare, have explicit rules on data protection. For example, the Gramm-Leach-Bliley Act requires financial institutions to let customers know how their data is being shared and also how their data is remaining protected.
Encryption helps financial institutions comply with this act. Encryption also keeps users safe while browsing the internet. Earlier in the internet's history, attackers found ways to steal unencrypted information sent between users and web services over the Hypertext Transfer Protocol HTTP. The standard to encrypt web content by running HTTP over the Secure Socket Layer protocol emerged, soon to be replaced with the Transport Layer Security protocol, enabling enterprises, publishers, and e-commerce providers to offer a secure experience for users.
With encryption, users feel safer entering personal information into webpages and carrying out financial or e-commerce transactions. Encryption will continue to be a core security feature in everything from video chats to e-commerce to social media.
Basically, if it can be shared or stored, it will be encrypted. Both organizations and individual users would benefit from keeping on top of encryption standards to ensure that both their personal and professional data is safe from misuse or compromise.
