Categories of data leakage
There are two basic categories of data leakage: "inside" and "outside" information, with different methods applied to each. Inside information is any information generated by the company itself, such as customer, source code, or proprietary documents.
This kind of sensitive information can be easily identified as it has a high volume and is categorized in a particular document type - for example, PowerPoint presentations, spreadsheets, or letters.
Outside information leaks correspond to any transmission containing outside-originated material such as news articles, competitor press releases, or informal/unauthorized communication. While more challenging to detect due to its lower volume and less specific categorization – this type of leak does not have defined rules regarding sensitivity levels of various kinds of documents which make detection difficult.
Email security software can be divided into two main categories - Cloud-based DLP and on-premises DLP. Cloud-based DLP is based on APIs where data leakage occurs in real-time.
This type of system is most effective when implemented by a cloud service provider having large, accurate databases with rules set up using artificial intelligence (AI) or machine learning algorithms that recognize customer-specific sensitive information.
On the other hand, an on-premises solution is both more expensive and less efficient due to its need for adequate human supervision and intervention, which delays detection times. Moreover, compared to cloud-based DLP, this kind of software does not offer outbound email monitoring/control capabilities often included in hosted solutions - making them more suitable for high-risk customers.
Evaluating data loss prevention software
When evaluating a DLP system, it is essential to consider how well it can monitor email traffic and other data transmission forms. Accuracy rates are another factor to consider as they indicate how many times the software will block legitimate emails even though they contain sensitive information - which could prove very costly for companies sending large volumes of messages.
Data leakage solutions should be evaluated based on organizations' criticality level, their compliance requirements, and the sensitivity levels various types of documents are assigned by end-users. As with all security measures, constant supervision will allow businesses to stay ahead of emerging threats.
Overview DLP systems monitor for possible leaking transmissions by identifying and blocking sensitive information. Data leaks are related terms and are often interchangeable. They represent an unauthorized disclosure of controlled data, in most cases without the owner's consent. Despite these risks, data leakage can be prevented without losing data from its original users.
Types of data leakage There are two basic categories of the most common types of data leakage: "inside" and "outside" information, with different methods applied to each. Inside information is any information generated by the company itself, such as the customer's private or confidential documents (source code or proprietary).
This kind of sensitive information can be easily identified as it has a high volume and is categorized in a particular document type - for example, PowerPoint presentations, spreadsheets, or letters. Outside information leaks correspond to any transmission containing outside-originated material such as news articles, competitor press releases, or informal/unauthorized communication. While more challenging to detect due to its lower volume and less specific categorization – this type of leak does not have defined rules regarding sensitivity levels of various kinds of documents which make detection difficult.
Types of Techniques Used by Data Leakage Prevention Systems
Data loss prevention systems use two main categories of technologies: "Static" and "dynamic." In the first case, software groups are sensitive by applying pre-defined rules-based systems. This type of technology is ineffective in the case of new documents without corresponding rules. Dynamic systems can learn from past analysis and identify likely risks, which can be especially beneficial for companies with large volumes of internal communication channels, such as instant messaging apps used by employees.
Email security software can also be classified according to its ability to control/monitor "inbound" or "outbound" information transmission online. An on-premises solution is more effective when stopping outgoing messages, but it tends to be expensive. On the other hand, cloud DLP solutions are less efficient at blocking outgoing emails due to limitations in email routing protocols -and this kind of capability requires additional costs associated with purchasing an advanced platform, adding outbound email monitoring capabilities, multiple licenses, etc...
Overview of the Benefits Provided by a DLP Solution
The most effective methods to prevent information leakage are not related to technology. Instead, the first step is to create proactive awareness within an organization's staff and reduce risks as much as possible through security policies, education programs, and sustainable development. Additionally, companies can implement advanced technologies such as data loss prevention systems, including industry-level encryption software and digital rights management (DRM). Digital Rights Management (DRM) refers to any access or usage restrictions that can be placed on digital content; it prevents unauthorized sharing of copyrighted material via internet transmissions by allowing only specific users to access and benefit from particular materials. DRM is especially useful in monitoring internal communications between employees trying to send sensitive information outside of the company.
How mature is your data security program
One of the main challenges for any business in today's competitive landscape is how well it manages its sensitive information. There are many ways to protect confidential, financial, and legal records against unauthorized access or disclosure, either accidental or intentional. One of the most simple yet effective forms of data leakage prevention is email encryption. Email encryption can turn an insecure communication - such as an email message being sent in plain text over the Internet where every point along the way could be compromised by bad actors if not adequately protected with solid algorithms that are very hard to crack – into a secure communication meaning that only sender and the recipient will be able to see its contents provided they have access to special software for decryption purposes.
Email encryption and data loss prevention (DLP) are two distinct concepts that help companies protect their sensitive information regardless of where it resides - on an organization's servers or the cloud - and their transmission coordinates throughout the entire organization's infrastructure. By applying encryptions to emails, businesses can ensure greater confidentiality between sender and recipient and within the mailing infrastructure by preventing unauthorized access to received messages regardless of where they are stored. Furthermore, DLP solutions use various forms of categorization for document types, allowing users to define rules on how securely each kind should be handled.
The first step towards email security has clear policies that apply not only to external collaboration tools but also inside your organization's email server – regardless of where employees access their email accounts. This means enforcing the use of encryption and strong authentication measures such as login passwords that include a mix of at least four letters, numbers, and special characters. Ideally, organizations should have their domain name whenever possible to limit the number of third parties involved in email transmissions. Data leakage prevention software is a vital tool for any company looking to improve the security of its digital information regardless of it's being used by suppliers or customers - allowing companies to self-regulate whether data is being sent through an insecure channel without requiring multiple layers of regulations which could prove very costly.
Reactive vs Proactive Defense
Businesses must adopt proactive defences to ensure confidentiality, integrity, and availability (CIA) of their information throughout the entire business infrastructure. This includes secure login passwords, data encryption, anti-virus software with regular updates to protect against new forms of malware, and intrusion detection systems that monitor network traffic for known threats, including DLP solutions for email servers designed to detect policy violations before they are sent out. Proactive security measures help provide a more secure environment by mitigating risks that could affect internal operations and preventing external threats from entering an organization's digital perimeter in the first place.
Businesses should turn towards user behaviour training once proactive measures have been deployed on an organization's servers and network devices – including email servers, firewalls, routers, gateways, etc. As most successful attacks rely on social engineering to exploit vulnerabilities within an organization's infrastructure, the best way forward after deploying proper security measures is to educate employees on common forms of email scams that are explicitly designed to trick users into providing access credentials or downloading malware onto their work computers.
Most successful data breaches that culminate into leaked sensitive information have been a direct result of weak detection systems failing at the early stages of an attack. This means ensuring all possible attack vectors are being monitored by proactive tools, including data protection and prevention software for email servers and intrusion detection systems for further analysis against current threats in real-time so action can be taken immediately - before it's too late.
Companies should also monitor outgoing emails for policy violations through DLP solutions that scan messages before being sent out, designed to detect confidential, personally identifiable information sent through insecure channels.
Email security requires a multilayered approach of not only preventing the possibility to detect sensitive data from lingering around servers but also assessing which users have access to that data - especially when they are outside of its intended destination. This means frequent user behaviour training on social engineering tactics, enforcing encryption for all forms of information transmitted throughout the entire infrastructure, and deploying alerting systems within the infrastructure itself to monitor for policy violations in real-time against current threats.
Once preventive measures are taken care of, organizations should look towards proactive tools, including DLP solutions for email servers. These are designed specifically to monitor outgoing messages for policy violations before being sent out, with the ability to block emails containing sensitive information to ensure confidentiality automatically. While email security can't prevent breaches from occurring once they have already happened, it can be deployed to protect against mistakes that could allow hackers to breach private networks in the first place.
King recently announced a new focus on ensuring all of its suppliers use encryption software for their cyber protection so confidential company information doesn't fall into unintended hands through insecure channels. Due to recent reports suggesting some third-party suppliers had been sending sensitive data, including passwords and other financial information, through unencrypted emails - often in plain text - King has stated that it will mandate compliance with these requirements by strengthening its supplier agreement terms within the next few months.
"We would like all our suppliers to use good cyber security standards, so we have a new clause in the supplier agreement which mandates a certain level of security on their side," Marten Pieters, King's chief technology officer, said before adding that King is currently working with suppliers to ensure they are complying with these requirements.
"We're doing this from a position of strength as well because we've been stronger on encryption for some time now."
The fact that consumer data will soon be protected by encryption legislation means it would only be fitting if all companies protecting user information took additional measures to protect data at rest and during transit - especially SMBs, which aren't required by law to encrypt anything. This equates to securing email servers against attacks and deploying DLP solutions designed specifically for email software - including Microsoft Exchange Server, IBM Notes, Oracle Communications Messaging Server, Lotus Domino Server, GroupWise, and other email servers.
"It's important to say that this is coming from a position of full force here - we are very aggressive with our encryption initiatives," Pieters said. "That being said, it is time for the industry to move forward on this front."
King has decided to take steps forward in its fight against the impending fragmentation of passwords and other sensitive information to protect user data. Instead, King wants to ensure that any form of sensitive data - including usernames, passwords, banking details, and additional financial information will be protected by a robust encryption algorithm which ultimately means adopting one-time use tokens for authentication purposes instead.
"We don't want this password situation," Pieters said. "It's not good from a security perspective because all you have is a string of characters which can be used for something else somewhere else."
