We are living in a digital world, one in which we rely on digital tools in virtually every aspect of our lives. From our personal computers to cell phones and tablets, even our thermostats and other home appliances rely on digital networks. Even our cars, ATMs, traffic signals and more rely on digital networking technology
But as our dependence on this digital work grows, so do cyber-crimes and data breaches. The importance of network security in business is taken for granted because, unlike devices, they aren’t tangible.
However, our devices, including cell phones tablets and even our cars depend on a reliable and secure network and are one attack away from disaster. Today’s digital world is stitched together by networks that connect all of our devices and are packed with sensitive data. There is a war raging, and the battleground is our cyber networks; It’s a constant battle between network security administrators and hackers as they battle for control.
Network Node Protection
A node is any device that is connected to any digital network with Wi-Fi or Ethernet connection. Nodes come in many flavors or types. At the enterprise level nodes comprise modems, ethernet hubs, printers, gateways, servers, personal computers, and standalone terminals. Financial and retail institutions, digital networks including ATMs, cell phones, tablets, servers, and databases. Private networks referring to home Wi-Fi networks with laptops and other mobile devices, such as cell phones and virtual assistants, such as Siri and Google Home Assistant.
Node protection usually comes in the form of various virus protection applications and malware protection applications. There are measures you can take to keep your network secure, but it is good network security practices to ensure all nodes have a local barrier against attacks. Security measures implemented at the node level act as a second line of defense and sometimes can isolate or quarantine infected viruses that slip through the network security front lines.
Sensitive Data Protection
Integrating technology in our modern lives, ranging from shopping at the grocery store to accessing healthcare records, requires more of our data to migrate through digital networks. There is no industry, company or educational institution immune to network security threats.
The importance of network security in business is paramount in today’s cyber climate. A data breach at the enterprise level can devastate corporations. The damage suffered from a public relations standpoint can cause catastrophic brand damage.
Data encryption is one of the most common and effective network security methods used among network administrators in today’s corporate environment. Sensitive data that is guarded by encryption, effectively renders information unreadable without a complex encryption key to make sense of it.
Advanced Encryption Standards are one of the most secure encryption algorithms available. The United States government uses AES to protect classified data. AES divides data into blocks and encrypts each block of data bit by bit. AES can be encrypted at the 128, 192, or 256 level. AES encryption requires sharing the decryption key with authorized users.
Triple Data Encryption Standard is a block cipher approach to securing sensitive data. Triple data encryption uses three individual 56-bit keys and is encrypted three times, so it’s 168-bit key encryption. It is projected, however, as encryption methodologies increase 3DES will be replaced with a more robust encryption standard.
Twofish data encryption uses 128-bit and 256-bit block sizes of encryption, and it’s typically used for personal CPUs and hardware on a smaller scale. Twofish is an open-source technology and does not require a license, which gives more flexibility on how and when it is used.
RSA is reserved for transmitting data over public networks. The RSA encryption flavor comprises two decryption keys: one public and one private. The public key is available to virtually anyone; however, the private key is given to individuals who have been granted access.
Shared Network Security
The ubiquitous nature of high-speed internet access has sparked an uptick in remote users at the corporate level. While giving employees the option to work remotely saves enterprises money and is convenient for the worker, it also poses a security threat. Remote users must have access to private networks, and network administrators must ensure that the private system stays secure.As part of the security measures taken with shared network access administrators should focus on areas within their control, such as strict rules on allowed users and devices connecting remotely.
Data recovery is crucial within an enterprise environment as it applies to a company’s ability to survive natural disasters and ransomware. By implementing effective data backup schedules, an enterprise ensures that any of these two unfortunate situations occur; they won’t miss a beat.
The importance of network security in business is a major priority, especially with ransomware attacks becoming more common among hackers. Unlike malware and viruses, ransomware is not rectified by the scanning of potentially infected areas. The best way to protect against ransomware is to prevent a breach in your network and regular data backups.
Typically, ransomware gains access to a private network using an email attachment or by accidental download. The best defense against ransomware is data backups, storing this data in a different location, and educating employees about the dangers of opening unknown emails.
If you are the unfortunate recipient of a ransomware attack network administrator should immediately identify and quarantine the infected areas. Restrict all power to the affected node and remove it from the integrated network. Once the infected node is isolated network administrator should assess the infected data and take proper precautions to discover how the bug gained access to the network.
If you have identified a ransomware attack on your network, after quarantining the affected node network administrator should immediately begin changing passwords and in some cases usernames. Great server administrators know it’s better to be safe than sorry. And if you need more help, check out how we help your business with it’s IT Security.
