For any company, data loss is paralyzing, especially in the Big Data Age, where companies rely on digital information to perfect their marketing, contact prospects and process transactions. Reducing data loss possibilities is a vital part of a data management strategy. Firstly, avoiding data loss should be the first goal.
There are many reasons that may lead to loss of data. So
- Accidental deletion
- Laptop stealing
- Fixed disk failures
- Computer viruses and malware infections
- Power failures
However, if a loss occurs, there are several best practices that can be implemented to increase recovery chances. Second, don’t put all the eggs in the cloud bin. Cloud is vital to economic storage, but it has some disadvantages that should not be overlooked.
An employee who has simply left his or her computer or hard drive has had many examples of data loss, so they should talk about best practices with staff members.
Main ways you can protect your data from loss and unauthorized access.
Backup beforehand and frequently
The most important step in protecting loss data is to regularly back it up. How often are you supposed to backup? It depends on how much data you can afford to lose if your system completely stops. A week’s work or a day’s work or an hour’s work
Differentiate your backups
You should have 3 backup copies of all the important things. They should have a backup in at least two different formats, such as on a hard drive and in the cloud. Offsite backup should always be available in case your physical location is damaged.
Use file level and security at a shared level
The first step is to set permissions on files and data folders to keep others out of your data. You can set sharing permissions to control which user accounts can and cannot access files on the network if you have data on network shares. This is done by clicking the Permissions button on the Share tab of the file or folder properties window with all versions of Windows.
These shared-level permissions, however, do not apply to someone who uses the local computer where the data is stored. If you share a computer with someone else, you must use file-level permissions.
In either case, you can set account or user group permissions and allow or deny full control of multiple levels of read-only access.
To perform basic backups, you can use the built-in Windows backup tool (ntbackup.exe). You can use wizard mode to simplify the process of creating and restoring backup copies, or you can set backup settings manually and schedule backup tasks for automatic execution.
Documents protected by password.
Several applications for document productivity, such as Microsoft Office and Adobe Acrobat etc., enable you to set passwords in individual documents. You need to enter the password to open the document. Go to Tools Options and click on the Security tab to protect a document in Microsoft Word 2003 or higher.
To open the file and/or make changes to it, you can request a password. Unfortunately, the password protection provided by Microsoft is relatively easy to crack. Market programs are available to recover Office passwords, such as Advanced Office Password Recovery (AOPR) from Elcomsoft.
This type of password protection, like a standard lock (without a latch) on a door, will discourage potential intruders, but an intruder with the right tools can easily avoid it.
To compress and encrypt documents, you can also use compression software such as WinZip or PKZip or 7Zip.
Use encryption of the disk.
There are several third-party products that enable you to encrypt a full disk. Full disk encryption blocks all drive / partition content and is transparent to the user. This will encrypt the data in Hard disk ,removable USB drivers and Flash drives automatically.
Some of these programs within a partition that acts as a hidden disk within a disk can create invisible containers. Other users see only the “external” disk data.
Protect IP security data in transit.
A hacker with software sniffer (also known as network monitoring software or protocol analysis) can capture data while traveling in the network. You can use Internet Protocol Security (IPsec) to protect your data when in transit, but both sending and receiving systems need to be compatible.
Microsoft operating systems versions of Windows 2000 and later have built-in support for IPsec. IPsec should not be known to applications as it operates at a lower network model level. Encapsulating Security Payload (ESP) is the confidentiality protocol used by IPsec to encrypt data.
It can work for end-to-end protection in tunnel mode, gateway to gateway protection, or transport mode. You need to create an IPsec policy and select the authentication method and IP filters to be used to use IPsec on Windows. In the Options tab of the advanced TCP / IP configuration, the IP sec configuration is configured via the properties window for the TCP / IP protocol.
Wireless transmissions are secure
Data sent through a wireless network is even more susceptible to interception than data transmitted through an Ethernet network. Hackers do not need physical access to the network or its devices; We need to configure wireless access point securely, otherwise anyone with a wireless laptop and a high-gain antenna will be able to capture data and/or access the network and access the data.
Only wireless networks using encryption. Preferably Wi-Fi Protected Access (WPA) is more powerful than Wired Equivalent Protocol (WEP).
