What Data to Mask using Data Masking?

The most frequent misconception on the subject of data masking is the thought that “our data is not appropriate for anonymization as many test databases require the original data. The real information might be necessary for single database – however, it is improbable to be needed in each test database.

  • Employ a Range of Data Masking Techniques: A logical procedure is to have a range of masking methods for varying objectives.These masking methods will be adjusted to the level of data exposure and the extent of regulations maintained.
  • Light Masking on a Fire-Fighting or Bug-Fix Database: One of the main

Application-layer filtering in Firewalls

A database firewall is designed to prevent particular kinds of traffic from passing through the external Internet network to the internal network. This facilitates the database administrators to manage what penetrates in the local network and keep unwanted data out. Besides filtering, this prevents internal users from transferring various forms of data, or transferring data to specified locations.

Application-layer firewalls can recognize the traffic passing through them and permit or refuse traffic based on the data content. Host-based firewalls intended to block unwanted content on the Web that is derived from keywords covered in the Web pages are a type …

How is a Database Firewall used?

A firewall is a method designed to prevent unauthorized access to or from a private network. The database firewalls can be applied to both hardware and software, or an arrangement of both.

Database firewalls are often used to thwart unauthorized Internet users from accessing the private networks joined to the Internet, particularly intranets. All messages incoming or outgoing the intranet pass through the firewall, which inspects every message and blocks the ones that do not fulfill the specific security criterion.

The key features of the firewall protection comprise the following:

  • Varied degree of protection based on the location of the

Key Data Masking Tools

Ever since the advent of private and sensitive information, there have been attackers that have tried to reach that data and use it for malicious purposes.

Many data masking software have been developed to make the task of accessing sensitive data ineffective. Each of the techniques has their strengths and weaknesses with each technique typically being best applied to a specific data type.

Following are the key data masking tools:

  • Substitution
    It refers to randomly substituting the contents of a column of data with entirely unrelated data, but the data looks identical to original data. Substitution is one of the

Database Firewall and Intrusion Detection

Firewalls are used to guard home networks as well as corporate networks. A standard firewall program or hardware device filters all data coming from the Internet to your network or computer system. Many types of firewall techniques will avert possibly unsafe data from getting through; intrusion detection is one of such technique which is available in many firewalls.

What is Intrusion Detection?

Intrusion detection is a highly developed feature of the firewall, and a lot of firewalls such as ICF are short of this feature. Intrusion detection systems (IDSs) can recognize attack signatures or patterns, cause alarms to aware the …

Learn the basics of Database Security

Though some attackers still concentrate on denial of service attacks and destruction, cyber criminals frequently target the database because that is where the wealth is. The databases sites hold a huge deal of valuable data for someone looking to steal credit card information or personal details.

Database security itself is an enormously profound subject that may perhaps never be covered in the course of one article, but there are only some best practices that can assist even the smallest of organizations protect their database enough to make an attacker shift on to an easier target.

Ways to Install Database Firewall

There are various ways to install enterprise firewalls, depending on necessities and the use cases for the device. If they are not rightly organized then, you’ll end up with either too many or too fewer boxes, single spots of failure, suboptimal network access, or inferior quality application performance.

We could talk about all sorts of different models and use fancy names like Tiered, mesh, peer to peer, and the like for them — but fortunately, the situation isn’t that complicated. To select the most suitable architecture you must consider few points:

  • Public or private network– It is necessary to

Structure of a Cyber Attack

When we include security features into our application’s design and execution, it helps to have a better understanding of the thinking process of attackers. The countermeasures can be applied more effectively by thinking like attackers and having an awareness of their possible strategies.

Having an understanding of the critical approach used by attackers to target your database network is helpful in better preparing for the protective measures. The key steps in attacker’s line of attack are summarized below:

  • Survey and Evaluate
    Surveying and evaluating the possible target are done in aggregation. The first typical step an attacker takes is to

Steps to Implement Data Masking

Data masking refers to obscuring particular records of sensitive data within the database. Masking of data makes sure that confidential information is substituted with realistic but not the real set of data in the testing environment. It helps in accomplishing both the aims – protecting sensitive data and making sure that test data is valid and testable. Data masking is not merely about Test Data. In fact, this approach applies to every situation where an organization does not want to expose real information.

There are many ways to implement data masking. It could be as a replacement of existing records …

Five Rules for Masking your Sensitive Data

Each data masking platform substitutes the data factors with similar values, optionally moving masked data to a new location. Masking generates a proxy data replacement which maintains a fraction of the value of the original data. The main point is to create data that looks and acts like the original data, but which is less sensitive and doesn’t pose a risk of disclosure, allowing the use of tight security control measures for masked data repositories. As a result of it, the scope and difficulty of IT security efforts are reduced. Masking should work with basic data repositories, such as files …
