Fighting Cyberattacks: 4 Powerful Ways to Protect Your Business

Cybersecurity is one of the leading issues in business tech. When the system is breached, your company can lose critical data and even face a total shutdown. Luckily, new technologies are emerging to provide better security against evolving cyber threats. We explore below some of the best measures you can take to ward off cybercriminals.

1. Data encryption 

Data encryption is the process of disguising sensitive information as “ciphertext,” making it unreadable and useless to an unauthorized person. It maintains the confidentiality of customer information, employee files, and financial records in case they fall in the wrong hands.

To unlock the encrypted data, you need to use the secret decryption key which is typically a series of numbers created with algorithms. It unscrambles the ciphertext and makes it readable. Each key is random and unique to ensure maximum protection. 

Confidential information that is leaked, shared, or stolen can pose serious consequences. Encryption protects your company from data theft and saves you from legal trouble. Thankfully, almost all operating systems nowadays feature full-disk encryption for all kinds of devices. 

2. Backup and recovery 

Data backup, also called operational recovery, involves creating and storing duplicates of relevant information in case of data loss. It’s an essential part of disaster recovery that allows businesses to retrieve data that has not been affected by corruption or malicious attacks. 

Backup copies should be stored in a separate system or medium to protect against primary data loss. Alternate mediums include external drive or USB sticks, disk storage systems, cloud storage containers, or tape drives.

Get in the habit of backing up your files on a weekly basis or whenever you acquire new and important data. Remember, physical mediums malfunction over time. Make sure you check the condition of your disks and hard drives at least once every month.

3. Up-to-date software

Outdated applications are more vulnerable to threats designed to steal data, invade networks, and cause major downtime on operations.

A company-wide, bi-weekly check on installed software can identify suspicious user activity or system errors indicative of potential threats. Regular inspections allow you to troubleshoot missing protective patches and vulnerable areas before they escalate into bigger issues. 

Be alert for updates when purchasing and installing new software. As much as possible, do not postpone operating system upgrades as they often introduce new or improved security features. 

4. Firewalls and anti-malware

According to a study from the University of Maryland, a hacker attack occurs every 39 seconds on average, affecting one in three Americans per year.

Firewalls and anti-malware software are two of the best weapons against viruses and attacks. Anti-malware tools identify and isolate viruses. They also provide quick scans of removable devices and incoming network data.

Firewalls, on the other hand, block hackers and other forms of malware from entering your database. Installing a firewall system on every networked device prevents employees from browsing inappropriate websites or engaging in suspicious activity. For best results, use of these tools should also be applied to remote employees.

Cyber attacks happen anytime and from anywhere. They can disrupt operations and even permanently damage your relationships with partners and clients. Following preventive actions can go a long way in saving your business from a digital catastrophe.

NAS Network Attached Storage

What does NAS mean?

NAS means Network-attached storage

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients

NAS is specialized for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance – a purpose-built specialized computer. NAS systems are networked appliances which contain one or more storage drives, often arranged into logical, redundant storage containers or RAID.

Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing files among multiple computers. Potential benefits of dedicated network-attached storage, compared to general-purpose servers also serving files, include faster data access, easier administration, and simple configuration.

The hard disk drives with NAS in their name are functionally similar to other drives but may have different firmware, vibration tolerance, or power dissipation to make them more suitable for use in RAID arrays, which are sometimes used in NAS implementations. For example, some NAS versions of drives support a command extension to allow extended error recovery to be disabled. In a non-RAID application, it may be important for a disk drive to go to great lengths to successfully read a problematic storage block, even if it takes several seconds. In an appropriately configured RAID array, a single bad block on a single drive can be recovered completely via the redundancy encoded across the RAID set. If a drive spends several seconds executing extensive retries it might cause the RAID controller to flag the drive as down whereas if it simply replied promptly that the block of data had a checksum error, the RAID controller would use the redundant data on the other drives to correct the error and continue without any problem. Such a NAS SATA hard disk drive can be used as an internal PC hard drive, without any problems or adjustments needed, as it simply supports additional options and may possibly be built to a higher quality standard (particularly if accompanied by a higher quoted MTBF figure and higher price) than a regular consumer drive.

What does BYOD mean?

BYOD means Bring Your Own Device

You used to have better stuff (computers, phones) than at home, since gadgets are so popular and accessible that it is increasingly common for people to have better (newer) stuff at home than at work. This is why BYOD is starting to become popular, and there are already companies that make a policy of making people take their own belongings. If someone with his own stuff works better or faster, then a boss often has no problems with people taking their own stuff, however it is often difficult to compensate financially for the electronics that people take with them.

What does NFC mean?

NFC means Near Field Communication

NFC is a wireless technology that should enable electronics to communicate with each other. This happens on a radio frequency that allows mobile phones, digital cameras, etc. Can communicate with each other over a distance of approximately 20 cm (at a rate of 212 kilobits per second). Both Philips and Sony also have smart cards with microprocessor that are intended for storing identification data or financiëe information. Read More
