PCI DSS standards meets the requirements of the GDPR?

The objective of both the PCI DSS and the GDPR is to ensure an organization’s personal data is in a secured manner. The main focuses of PCI DSS are on payment card and cardholder data, whereas the GDPR focuses on European residents’ personal data. The main difference is that the GDPR is less prescriptive than the PCI DSS.

The GDPR provides guidance on what needs to protecting but does not clearly defined a detailed action plan, but PCI DSS has clearly defined an objective that what needs to be achieved and given clear direction for securing the payment card and cardholder data.

The PCI DSS as standards to achieve the objective of GDPR 

Perturbed over login ID and password data breach? Not anymore!

In recent years, we have been hearing of numerous ‘Login ID’ and ‘Password’ related data breaches involving popular websites and other online services. It is also likely that your application credentials are listed in a massive file that is floating around in the Dark Web. These can lead to “Loss of Trust” with customers. Loss of Trust leads to ‘Loss of Brand Loyalty’ and eventually results in ’Loss of Business’.

Lets us see how these security issues can be encountered. Most of us will obviously come up with a solution toward multi-factor authentication and risk/behavioral authentication. This, apart from being the obvious solution that could pop-up, multi-factor authentication often creates conflict between ‘compliance requirements’ and ‘user convenience’. Ideally, we should be thinking about a solution to fortify the application security - without compensating on user experience.

IoT Security in 2018

The Internet of Things (IoT) offers the potential to exchange information and insights in real time, across a connected network.

The number of IoT devices increased 31% year-over-year to 8.4 billion in 2017 and it is estimated that there will be 30 billion devices by 2020. The global market value of IoT is projected to reach $7.1 trillion by 2020.

IoT involves extending internet connectivity beyond standard devices, such as desktops, laptops, smartphones and tablets, to any range of traditionally dumb or non-internet-enabled physical devices and everyday objects. Embedded with technology, these devices can communicate and interact over the internet, and they can be remotely monitored and controlled.

Gartner identifies the top 10 Internet of Things (IoT) technologies as below:-

Session Puzzling : Solving the puzzle!

Session puzzling is an application level vulnerability that occurs when the application session variable is using more than one purpose. The other name of session puzzling is session variable overloading.

The attacker tries to access application entry points. The session objects creation can be indirectly initiated while exploiting session puzzles, and later exploited, by accessing an entry point such as web services, web pages, remote procedure calls, etc.

Session puzzle enables the attackers to bypass authentication, Impersonate legitimate users, elevate privileges, bypass flow restrictions, and even execute additional attacks.

Machine Learning in Cyber Security

Nowadays, every single human activity is connected to a digital system. But these digital systems always rely on the programming language. Based upon the previous activities, the system can analyze and learn the data to be processed without any human interaction, this concept leads to a technology called machine learning.

In the case of Cyber Security, Machine Learning technology helps to analyze previous Cyber Attacks and develops the protective response accordingly. The Cyber Security is one of the latest sectors with the huge investment in machine learning based on the response to increasing cyber threat.

In the past, Cyber Security was not very familiar with Machine Learning.  Network administrators were struggling with finding and tracking attacks. It looks a lot of time for them to even detect an attack. 
Now, there are many security software that has been developed to support the human in order to maintain the System effectively.

Bluetooth Security Flaw Could Allows Nearby Hackers to Steal Your Data

Bluetooth Security Flaw Could Allows Nearby Hackers to Steal Your Data

A newly discovered bug in Bluetooth implementations and operating system drivers allows hackers to gain unauthorized access to a device and steal data. 

Bluetooth firmware or operating system software drivers may not adequately validate elliptic curve parameters used to generate public keys during a Diffie-Hellman key exchange, which may allow a remote attacker to gain the encryption key used by the device.

Hackers get access to the data by forcing a device to use a known pairing key. For instance, when pair phone with computer, it might be prompted to enter a five-digit code. Hackers leverage that code to intercept information when pairing the device again. This flaw is different than the BlueBorne virus that cropped up last year, which allowed hackers to gain control of a device using its Bluetooth connection. 

Why depending on RDNS is bad and not to trust client provided Destination IP address for Name Lookup in Transparent Proxy Deployments!

As everyone knows that forward DNS is used to get the IP address from the Domain name (maps a domain name to an IP address) whereas Reverse DNS is used to get the hostname from the IP address (maps Ipv4 address to the CNAME on the host) which uses Pointer records to get this.

When the bluecoat ProxySG is configured to allow or deny the access to URL's, it must determine the hostname of the site being requested.

In Explicit Deployment:

When it is an HTTP site, the proxy simply observes the HTTP request headers to determine the hostname of a website.

When it’s an HTTPS site, the communication will be encrypted via SSL.

Data Classification and Retention Policy : Points to consider while framing Retention Policy (GDPR)

Data Classification, in general, is labeling of data and protect data based on the sensitivity and how much it has an impact on the organization when there is a breach. This will have 2 parts to it. One is under what type the data is classified and second is the risk that possesses.

Data Type Classification can be customized based on the customer we work for; however, Data risk Classification is universal and common among most organizations such a PUBLIC, INTERNAL, RESTRICTED, SENSITIVE and SECRET.

GDPR and Privacy Management : Are you GDPR compliant?

The General Data Protection Regulation (GDPR) (EU) 2016/679 is a regulation in EU law on data protection and privacy for all individuals within the European Union (EU) and the European Economic Area (EEA). It also addresses the export of personal data outside the EU and EEA areas. The GDPR aims primarily to give control to citizens and residents over their personal data and to simplify the regulatory environment for international business by unifying the regulation within the EU.[1]
