What Is Email Masking?

By

On November 26, 2021

In Security

Email masking is a method of changing email addresses to keep sensitive information from being abused. In most cases, a disguised email address retains its original format and cannot be traced back to its source. Email masking is often a part of a larger data masking process that hides sensitive data. The objective is to keep the true information hidden from prying eyes. Email masking can be used for a variety of purposes, such as:

  • To test software or shuffle real user data.
  • Ensure the security of any user data being shared with other parties.
  • Observe privacy regulations and safeguard data in accordance with the standards.
  • Entering masked email addresses on platforms you don’t trust.

In the end, it comes down to whether you want to disguise your personal email address or whether you have a database of user addresses that need to be hidden. Regardless of the reason, this includes the data you keep as well as any copies you make of it. And there are lots of good reasons to make new copies of your users’ information.

The two most frequent techniques of data masking are as follows:

  • Static email masking: Allows you to duplicate a database with data that is identical to the original one. The copied data is then transformed into a new set of data using SQL queries. The objective is to produce realistic records without exposing critical information, as it will be used mostly for testing and development.
  • Dynamic email masking: No copies are generated. Production data is protected with additional layers of security. The major purpose is to ensure role-based database security.

Even though you use the most advanced techniques for concealing genuine email addresses and spend hours modifying your data, something could go wrong at some point. You might miss some records in your database or submit the wrong contacts unintentionally. Some emails may be mishandled by the masking method, and inaccuracies may be difficult to detect in huge data sets. You can mask emails from within your email client if you don’t want to utilize any additional software.

Gmail: Gmail has two features that might be useful:

To begin, add words after the ‘+’ symbol to create aliases of your actual email account. The email address abcdefg@gmail.com, can have the following aliases:

abcdefg+breakingnews@gmail.com

abcdefg+important@gmail.com

You can also send emails from a different address using Gmail.

Outlook: Free aliases and a customizable “From” field are also available in Outlook. To make an alias, go to the Add an alias option and establish a new Outlook.com account. An existing email account can also be used as an alias. Send and receive emails to and from your personal Outlook account. You may send emails from this alias or the account you just added, just like you could with Gmail:

  • Open the Compose window, select “Send From” from the three dots.
  • Then, from the list, choose the required email address.
  • Open ‘Settings’ -> ‘View all Outlook settings’ to alter the default “From” address.
  • Choose ‘Sync email’ from the ‘Mail’ section of the ‘Options’ pane.
  • Finally, in the ‘Set default From address’ section, select the desired email.

You can unmask any email address you want at any time and resume sending from your original account.

Things To Consider While Upgrading Office Network

By

On October 30, 2021

In Security

Business-grade office networking solutions has crucial productivity, security, and functional characteristics that make the solutions a preferred choice for all enterprises. As the organization grows or there is an advent of newer technology, businesses should consider upgrading their office networks.

While upgrading their office network, businesses should invest in high-quality network equipment that features: –

  1. Intelligent Networking – Networks aided by RPA (Robotic Process Automation) and machine learning provide maximum performance on applications and services. The intelligent system can adapt, learn, and defend itself is an AI-enabled network.
  2. Multiple Wireless Network Support – A single wireless network is often supported by consumer access points. Multi-wireless networks, often known as SSIDs (Service Set IDentifiers), are supported by business-grade access points. This allows versatility and protection. Inbound-outbound rules, encryption, authentication, and other features can be applied to such SSIDs to provide an extra layer of protection. Additional dedicated SSIDs guaranteeing network isolation and congestion-free communications channel are formed for IP cameras and wireless speakers. Office owners can also utilize dual-band routers with 2.4 GHz and 5 GHz bands.
  3. NAS (Network Attached Storage) – A NAS is a data storage device. It’s a box with many hard drives configured in a RAID array to defend against hardware failures and faults. A network interface card connects directly to a switch or router and allows data to be accessed through a network. Data may be accessed using a shared drive from desktops, laptops, and servers. With NAS, there is no need to store copies of your papers on all of your assets and devices. It allows operators and business owners to deploy virtual computers and set up a media server that can stream to any device in real time.
  4. Network Security – Physical network security is the initial layer, and it should keep unauthorized people out of physical network components. Access to network components must be logged, controlled, with mandatory biometric verification requirement. Technical network security is the second layer, which safeguards data in transit as well as data at rest. External threat actors as well as harmful insider activities can be mitigated implementing a VPN and/or two-factor and multi-factor authentication techniques. Antivirus and firewall software must be updated to only allow access to authorized staff. The administrative network security layer is the last layer, and it comprises of security rules and processes that regulate network user behavior. Unauthorized network access to specific applications and devices is limited by unified endpoint management.
  5. Cloud Computing – The distribution of services through the internet is referred to as cloud computing. Software, storage, analytics, and servers are all examples of internet services that are referred to as “the Cloud.” A cloud provider will host and keep the data for all of these services in the end. Access to applications, servers, and data is no longer restricted locally, making remote work easier. Threat actors finds it more difficult to infiltrate the network on the cloud. Both employees and the corporation benefit from a cloud-based network as they can utilize file sharing, screen sharing, and team messaging over the cloud network. When deciding on a team collaboration tool, compare the benefits and drawbacks of the vendor products shortlisted. Another advantage for employees is that cloud computing decreases the workload of the network administrators and allows them to focus on other activities.

Data Security For Small Business

By

On October 27, 2021

In Security

Businesses of all sizes may use Internet to access and use different computer-based or cloud hosted tools and databases to work efficiently. This makes it important for businesses to have data security as a part of their overall strategy. Small organizations may safeguard their on-premise data by fulfilling these five requirements:

Gathering, categorization, and storage of data

Create a centralized list of various kinds of data collected, collection procedures and storage facilities available and in use. Verify whether the collected data is stored safely and is secured by various authentication mechanisms. Sensitivity of every kind of data varies on the basis of a lot of parameters. Email lists, for example, must be protected, but their level of confidentiality is far lower than that of customer records, such as Credit Card information. By classifying data according to confidentiality and the consequences if their privacy is compromised, you may obtain a sense of what your security program requires.

Law of the land

Depending on your sector of work and your business location, you may be subject to legal compliance
obligations. These are the rules that govern how you get, manage, store, and transmit sensitive data. These
may alter based on your industry, geography, and who or where your customers are. Business owners must
clearly describe the infractions and their repercussions, which must be read and understood by all workers.

Threats and dangers

A risk assessment aids in the discovery of flaws in the security implementation strategy. Determine what forms of personal data are regulated and what efforts are being done to ensure compliance. It’s important to examine the risks that unregulated PII poses to reputation, competitiveness, security, and other factors. From the most likely to the least likely, threat sources are rated. Controlling procedures and precautions are examples of risk management approaches you may apply. Insider threats are sometimes disregarded because they aren’t always carried out maliciously. Negligent behaviors and errors, which are also insider risks, can lead to a data breach or data destruction. The outcome usually costs regulatory fines, reputational damage, and financial loss to the business. Security solutions to protect against both unintentional and intentional insider attacks is a must.

Data retention and disposal

Data is stored and saved by any business for a certain period of time as deemed fit to their business application and compliance requirements. While saving as much data as possible may seem like a good thing, confidential data can become a security risk if left unmanaged. Examine your organization to discover what data may be deleted. Customers who have moved away, or had their service terminated, as well as old personnel data, are just a few examples. People who have asked for their personal information to be removed and data discovered on unused devices or in accounts that have been abandoned. Data, especially PII, accumulates over time, “cleaning your house” can both save you money and reduce your risk.

Policies should be reviewed, updated, and upgraded

Examine your entire security program to determine which safeguards need to be updated. Similarly, make sure you’re using the most up-to-date technology and solutions to safeguard sensitive data. Setting up SOCs and NOCs, as well as developing holistic IT strategies, can help firms stay one step ahead of attackers. As a result of the introduction of new data privacy legislation, your policies may need to be revised. Examine your internal security policies and develop policies that include best-practice security procedures. Maintaining compliance with the SOC2 framework and CIS benchmarks criteria helps ensure the security of the data you store and handle.
