The 128-bit IPv6 addressing format offers 340 sextillion IP addresses, making it extremely future-proof. But, that’s not all; IPv6 is also considered a protocol of better reliability, security and privacy. Also, IPv4 packets are often blocked by corporate firewalls because they could potentially carry malware.

Today’s networks, whether they have IPv6 deployed in them or not, are largely IPv6-compatible. All modern operating systems and network devices employ IPv6 dual-stacks, in which IPv6 is turned on by default.

According to the State of Internet IPv6 Adoption Visualisation published by Akamai, India tops the list of all countries with 59.7% IPv6 connections.

How Does IPv6 Handles Many Security Concerns upfront?

Actually, IPv6 is vastly different from IPv4, often in complex and subtle ways.

(1) The IPv6 operating systems create automatically two IPv6 addresses.

One IPv6 with randomised MAC address in the suffix to hide the device identity and be used for web surfing so that nobody can identify who is connecting to its web site.
And another IPv6 with real MAC address which is only used for end-to-end encrypted applications. Such services, for the time being, are non-existent but will be available with the next wave of internet innovations.

(2) IPv6 has a privacy protocol to protect end-user privacy.

The current internet (v4) lacks effective privacy and effective authentication mechanisms beneath the application layer. IPv6 remedies these shortcomings by having a few integrated options that provide security and privacy services.

(3) IPv6 can run end-to-end encryption.

While this technology was retrofitted into IPv4, it remains an optional extra that isn’t universally used. The encryption and integrity-checking used in current VPNs, especially required for work-from-home applications, is a standard feature in IPv6, available for all connections and supported by all compatible devices and systems. Widespread adoption of IPv6 will, therefore, make man-in-the-middle attacks significantly more difficult.

(4) IPv6 also supports more-secure name resolution.

The Secure Neighbour Discovery (SEND) protocol is capable of enabling cryptographic confirmation to confirm the identity of the host at the time of the connection. This renders Address Resolution Protocol (ARP) poisoning and other naming-based attacks more difficult.

And, while it isn’t a replacement for application or service-layer verification, it still offers an improved level of trust in connections. With IPv4, it is fairly easy for an attacker to redirect traffic between two legitimate hosts and manipulate the conversation or, at least, observe it.

(5) IPv6 promises better reliability and security

As IPSec, a protocol for authenticating and securing all IP data, is built into IPv6 as a default. Though IPv4 also offers IPSec support as an optional feature, it is mandatory in IPv6. IPSec consists of a set of cryptographic protocols designed to provide security in data communications.

IPSec has some protocols that are part of its suite: AH (Authentication Header) and ESP (Encapsulating Security Payload). The first provides for authentication and data integrity, the second, in addition to these, also for confidentiality.

Cyber security protects the integrity of a computer’s internet-connected systems, hardware, software and data from cyber attacks. Without a security plan in place hackers can access your computer system and misuse your personal information, your customer’s information, your business intel and much more.

5 Spheres Of Cybersecurity

1. Critical infrastructure security

Critical infrastructure security consists of the cyber-physical systems that modern societies rely on, e.g., Electricity Grid, Water Dams, Water Purification & Distribution, Traffic Light Systems, Shopping Complexes, Hospitals, etc.

When the infrastructure of an electricity grid interacts with internet, it becomes vulnerable to cyber-attacks. A organizations with responsibility for any critical infrastructures must perform due diligence to understand the vulnerabilities and protect their operations against them. The security and resilience of this critical infrastructure is vital to our society’s safety and well-being.

2. Application Security

Application security is the process of making apps more secure by finding, fixing, and enhancing the security of apps. Much of this happens during the development phase, but it includes tools and methods to protect apps once they are deployed. This is becoming more important as hackers increasingly target applications with their attacks.

Application security is getting a lot of attention. Hundreds of tools are available to secure various elements of your applications portfolio, from locking down coding changes to assessing inadvertent coding threats, evaluating encryption options and auditing permissions and access rights. There are specialized tools for mobile apps, for network-based apps, and for firewalls designed especially for web applications.

Types of application security softwares:

# antivirus programs
# firewalls
# encryption programs

3. Network Security

Network security guards your network against unauthorized intrusion due to malicious intent whether from inside or outside over internet. It ensures that your internal networks are secure by protecting the infrastructure and inhibiting access to it.
To help better manage network security monitoring, security teams are now using machine learning to deep learning so that they can flag abnormal traffic and alert to threats in real time. Network administrators continue to implement policies and procedures to prevent unauthorized access, modification and exploitation of the network.

4. Cloud Security

Cloud security is a software-based security tool that protects and monitors your data in your cloud resources. Cloud providers are constantly creating and implementing new security tools to help enterprise users better secure their data.

The myth flying around cloud computing is that it’s less secure than traditional approaches does not hold true. People used to believe that their data is more secure when stored on physical servers and systems they own and control. However, it has been proven through cloud security that your control does not mean security and your accessibility matters more than physical location of your data.

Cloud computing security is similar to traditional on-premise data centers, only without the time and costs of maintaining huge data facilities, and the risk of security breaches is minimal.
In fact, some vendors are offering cloud-based security solutions (SECaaS) to their clients. Recently I have shared a post about SECURITY As A Service with you.

5. Internet of things (IoT) security

IoT refers to a wide variety of critical and non-critical cyber physical systems, like appliances, sensors, televisions, wifi routers, printers, and security cameras.

IoT’s data center, analytics, consumer devices, networks, legacy embedded systems and connectors are the core technology of the IoT market.
IoT devices are frequently sent in a vulnerable state and offer little to no security patching. This poses unique security challenges for all users.

You need to know that

^ Security is one of the biggest barriers to great IoT adoption
^ Enterprises would buy more IoT devices on average if security concerns were addressed
^ Enterprises are optimistic about IoT’s business value and growth

Anything connected to the internet is at risk.

Overall, Cyber security is essential to govern the conducts and manners of interacting with computer systems from suspicious behavior. In a world where even our kitchen appliances and cars are connected to the internet, cyber criminals have endless opportunity to cause chaos.

As hackers continue to adapt to progressing technology, so will the IT security experts whose main focus is to keep our data secure. Take advantage of these 5 types of cyber security methods and protect your business from cyber attacks.
