What does Extended Validation SSL Certificate mean?

EV SSL is a popular type of SSL Certificate. Extended Validation SSL Certificate provides trust and security to the website. Let’s explain a little bit more about it.

What is an SSL Certificate?

Secure Sockets Layer, or SSL for short, is a standard used for encrypting data exchanged between users’ devices and websites. Additionally, it verifies identity for users to feel more secured. As a result, SSL is a useful security layer mainly for websites that ask for sensitive data from their users. Therefore, it is essential to transfer data without any risk of manipulation or interception.

SSL operates through two separate keys, a public key and a private one. Both of them are necessary to encode and decode the data that is flowing between two systems.

When a user reaches a website with an SSL certificate, there is a transfer of public keys to encrypt the communication between them successfully. Once the server gets a message, it decrypts it with its private key. The answer it returns to the user is also encrypted with the private key. Next, a mirrored process is required on the side of the user.

Typical usage of the SSL certificates is for websites, email, remote login, and so on.

EV SSL Certificate explained.

Extended Validation SSL Certificate or shortly EV SSL provides a really robust encryption level. Additionally, great security and the organization’s reliability authentication. However, to receive such a certificate, a globally standardized identity verification process is required. Besides, the owner has to determine exclusive rights to manage a domain, prove its legal, operational and physical presence, and show the entity has authorized the issuance of the certificate.

Typically, companies looking for this certificate are working with many constant transactions. Therefore, they demand to fully guarantee security for their users and protection for every payment or data transfer. Such companies are banks, financial institutions, big e-commerce enterprises, global brands, government, tech firms, etc.

Other types of SSL certificates

Domain Validation (DV SSL) is more simple to get, and it is also cost-effective. With it, you receive a basic level of encryption and security. The Certificate Authority (CA), for example, is going to verify through email the accuracy of the owner of the registered domain name. The CA will check if the email you gave matches the one recorded for the particular domain in the WHOIS record. Then you as a domain owner are going to receive a message, and in case your reply is appropriately taken, the DV SSL certificate is issued fast. Finally, you are going to receive it included in a file, and you are able to attach it to your website, and you are ready.

Domain Validation SSL certificate is for websites that are not handling sensitive data of their users, for example, portfolios or blogs.

Organization Validation (OV SSL) is more pricey rather than a DV SSL certificate. Also, the process to receive one is more time-consuming because it’s more exhaustive. On the other hand, OV SSL gives a better encryption level, and it securely verifies a company’s integrity and legitimacy. The CA is going to check the company’s information, such as name, telephone number, domain ownership, and physical address, and determine if there is fake data. In case the CA defines the company as genuine, the OV SSL certificate is going to be issued in a couple of days.

It will simply present the company’s name, city, state, and country where it functions. Typically, larger corporations or also government agencies apply this type of certificate.

A Multi-domain SSL certificate is a helpful method to receive encryption and security for the main domain name and various subject alternative names (SAN) by a single certificate. Security could even be an Extended Validation SSL Certificate for every domain you add. It saves time and money, and you can add or exclude the SAN you want. Companies with a presence in many locations, international enterprises that own various top-level domain names (TLDs) usually benefit from it.

What does IPAM mean?

Our current world depends a lot on IP addresses. Without them, networks can’t communicate, people’s devices can’t access networks, the Internet of Things can’t connect, cloud computing can’t work properly, etc. So the dependency of IP addresses is clear, isn’t it? 

IP addresses are demanded for many different purposes, daily and in massive amounts. As a result, their management has become an annoying headache for administrators in charge of the task. Just this can get you hours busy since we talk about hundreds or thousands of IP addresses if the network is extensive.

In this context, IPAM is hope, a great solution you should know because IPAM means IP address management! 

What else does IPAM mean?

Internet Protocol Address Management (IPAM) means software for planning, administrating, and monitoring the information related to the IP address space on networks. This software is an efficient tool, with a practical interface, for automating the IP addresses tasks that must be executed on a daily basis. It considerably reduces the chances of human errors while manually registering information on the typical spreadsheets.

For instance:

  • Administration of DHCP and DNS. The first provides and the second resolves IP addresses to hosts in TCP/IP type of networks.
  • Search of available IP addresses.
  • Supply IP address for devices to get connected to the network.
  • Finding and reclaiming abandoned IP addresses on a network.
  • Monitoring IP addresses’ status to register their details.
  • Reservation of unique IP addresses.
  • Providing the hostnames associated with IP addresses. 
  • Real-time visualization of subnets and devices using them.
  • Automatic updates of IP addresses.
  • Showing the routers used by each device connected to the network.
  • Automatic creation and clearing of DNS A records and PTR on virtual machines. 
  • IP management for virtual environments.
  • Reporting mismatched DNS entries, IP addresses issues, available capacity of subnets, etc.
  • Changing subnets and websites from IPv4 to IPv6. 
  • And much more!

How does IPAM work?

IPAM software is a service supplied by different vendors on the market. You can find paid but also free choices.

IPAM needs information from important components of every network to operate: the Dynamic Host Configuration Protocol (DHCP), the Domain Name System (DNS), and IP addresses.

Besides, IPAM uses the Internet Control Message Protocol (ICMP) input to obtain details from all machines on the network. The simple network management protocol (SNMP) to get and order data related to IP network devices.

Additionally, IPAM has efficient tools for monitoring. Through this combo, the software can manage the IP address space of a network. IPAM creates a very well-organized and accessible database with all the information and statistics it collects and produces.

Pros of IPAM.

  • Ease of use. You can control the software and all its settings from a friendly interface.
  • Automated and more efficient administration of the address space.
  • Clear visibility of all IP resources.
  • Automation of DNS-DHCP configurations, real-time updates of hosts connecting and disconnecting from a TCP/IP network. Detailed reports.
  • Higher reliability while reducing the chances of misconfigurations, overlapped subnets, IP addresses conflicts.
  • DNS/DHCP/RIR integration to IPAM allows it to update A DNS records and lease information efficiently.
  • Prevention of security breaches. Permanent monitoring and visibility IPAM provides of all network resources help protect from malicious activity.
  • Detecting issues and fixing them is easier and faster since it doesn’t have to be done manually. 

Conclusion.

IPAM means higher productivity for your network. Put it in charge of the routine tasks to focus on the biggest challenges of your business. Do you need more reasons to give IPAM a try? 

IPv4 address: Structure and examples

IP address explained

Each component that is included in a network needs an IP address as an identifier. To connect to the Internet, you receive from your Internet service provider (ISP) a public IP address. To operate successfully, servers have a public IP address too. In other cases, computers, devices, smartphones require a private IP address to connect to a private network.

IP addresses help with identifying devices connected in any kind of communication. Furthermore, they give information about the location of the devices in the network, making them capable of exchanging data and communicating.

What is IPv4 address?

Can you imagine IPv4 has been around since the early 80s? It is the 4th version of Internet Protocol which was launched in 1981. Its purpose is to set the rules for communication, such as how the data packets should be sent or how they should have to be received. 

IPv4 has one key characteristic, which is to apply the best-effort delivery model. It is not required to set prior adjustments between the two endpoints for the connection to operate successfully. Instead, it is possible to try to send a message and not wait to notice if it was sent successfully or not. That is the reason why it is excellent for the Internet.

IPv4 addresses are short and actually easy to use. They serve as an ID card of any connected host.

Structure of IPv4 address 

Every IPv4 address has a structure, which looks like that: x.x.x.x. The x represents an octet and is a decimal value from 0 to 255. Periods separate the different octets. Thus, each IPv4 address includes four octets and three periods. The IPv4 address is a 32-bit number and uniquely recognizes a network interface on a machine. The digits are formatted as four 8-bit fields divided by periods. Thus, every 8-bit range describes a byte of the IPv4 address. This way of interpreting the bytes of an IPv4 address is commonly introduced as the dotted-decimal format.

These are simple examples of valid IPv4 addresses:

  • 1.2.3.4
  • 31.142.173.104

The bytes regarding the IPv4 address can be divided even further into two parts. The first one is the network part, and the second one is the host part. 

Let’s take, for example, the IP address 1.2.3.4 

The first component characteristic of a typical IPv4 address, the network part, is represented with the first two octets and first two periods –  1.2.3.4 

The other component, the host part, is expressed with the third and fourth octets and the third period – 1.2.3.4

Network Part

The network part defines the specific number, which is delegated to a particular network. Furthermore, it also can identify the class selected for the network.

Host Part

The host part of the IPv4 address is the one is selected for every host 

With it is possible to identify a specific individual device on a particular network. It is important to know that for every host on your network, the network part of the IPv4 address will be identical, and the host part is going to be different.
