What is MySQL?

MySQL is the most popular database used in web applications. It’s free, easy to administer and is supported by all hosting providers. There’s a common issue that MySQL servers face and that is high server load due to high memory issue.

Why does MySQL consume high memory?

  1. Application software like Python, PHP, JAVA threads utilize more memory when configured improperly or un-optimized queries, complex coding, etc.
  2. Due to improper configuration of MySQL, it leads to inefficient memory or wastage of memory.

GLIBC GHOST – How to deal with it?

Glibc ghost

A critical vulnerability in the glibc library has been announced by Red Hat Product Security, assigned as CVE-2015-0235 and is commonly called as ‘GHOST’.

What is GHOST? 

A buffer-overflow bug, GHOST affects the gethostbyname() and gethostbyname2() function calls in the glibc library. A remote attacker can make an application call to either of these functions to execute arbitrary code with the permissions of the user running the application.

Impact of GHOST

The gethostbyname() function call is used for resolving DNS which is a very common event. This vulnerability can be exploited by an attacker by triggering a buffer overflow by offering an invalid hostname argument to an application that performs a DNS resolution.

CSF is Blocking Your IP? Here’s What You Can Do?

CSF blocking IP

Generally, considered to be an advanced firewall, CSF blocks external IPs (Inbound Connections) to avoid Brute force attack or attack similar to that (Multiple login failures, hacking attempts, etc.) on a server. The firewall might block the connection while uploading files using Filezilla.  It might be possible that Filezilla is trying to open multiple simultaneous connections to speed up the transfer. The firewall may interpret it as brute force or port scan activity and block the IP address from where the connection is originating.

8 Steps to Ensure DRaaS is Implemented Successfully

8 steps for DRaaS implementation

Planning to activate disaster recovery as a service? That’s a crucial step for your business. Evaluating the business requirements for DR by revising the business impact analysis (BIA) results that identify mission-critical IT assets and data is important prior to applying for DR as a service. Through the results of BIA, you can get specified recovery time objectives (RTOs) and recovery point objectives (RPOs) for your mission-critical IT assets.

Ensure that the vendor is an expert and is able to support your RTOs and RPOs. After the evaluation, analyze data and determine the tasks of the DR as a service vendor – for instance – server backup, data backup, DR plan development or DR plan testing.

Learn to Perform Virtual Disaster Recovery with this Simple Guide

Virtual Disaster Recovery

Today, organizations completely depend on the virtual machines for storing their critical data as well as applications and need them to always remain available. This is where the virtual disaster recovery comes into the picture. Virtual disaster recovery focuses on taking the backups of the virtual machines instead of the physical servers. VM backup can be taken in three ways – image-based, agent-based and server-less backup. Data replication helps the workloads to move independently between VMs and arrive rapidly after recovery, without the need of manual re-launching of OS and application on a physical server.
