Repair of non-functional websites
Repair of corrupt databases
- about -
The function of the database is to collect, update and manage all necessary information regarding the content of the website, and it is necessary to preserve that information. Repairing a website database without losing existing data is a service that involves:
- Repairing a database in which there has been a corruption (defect database structure), and comes to the termination of the website. Correction of errors that occur in this case is not automated, so that all adjustments and repairs work exclusively manually.
- Salvaging data in corrupt database, the data that is an integral part of the website and without which its smooth operation is impossible. Salvaging the database implies fixing and restoring the database when corruption occurs.
A database is a means of organizing information so that it can be easily managed, updated and retrieved. When it comes to websites, the database organizes the data for use with Content Management Systems (CMS). Each CMS has a distinct way of using database to retrieve information on images, texts, login credentials, settings etc.
Most common causes of database corruption or database loss could be:
- Hardware failure
Hardware failures can be caused by power outages, physical damage, or a logical failure. Such failures can lead to the loss of the database, and it is necessary to back up regularly. Hardware failure is considered to be one of the common causes of data loss.
- Human error
Most of the processes related to the functioning of the database are automated, but there are still many operations that need to be performed manually (PHP coding or SQL commands). That could lead to some of the data being accidentally deleted or modified in a way that prevents the website from interacting effectively with the database. Human error is the most common cause of data loss.
Cyber-attacks are the biggest threat to databases today, and for this reason it is imperative that security measures are in place. Results of cyber-attacks can be: theft of data, damage to database structures, data modifications, or even loss of the entire database.
The main reason for the database to be sound is economical. Damage or loss of the database presents major problems for the business, such as: loss of critical data related to the smooth operating of all applications and functions, “crash” of the website resulting in economic loss to the company, as well as negative impact on its image.
In other words, a website that has a healthy database is a website that brings in profits and maintains reputation.
Debugging the codes
- PHP, JS, HTML and others -
Since today’s scripting tools in various programming languages have systems for pointing to or correcting code errors, it can be assumed that today’s scripts on web pages are quite correct. However, an error that is not obvious and not automatically reported to the developer may go unnoticed. Such a hidden bug is called a “bug” and can produce an incorrect or unexpected result and make the website behave in unanticipated way.
Most software errors are due to errors in the source code of the program or its design, or in the components and operating systems used by the programs. Websites are a combination of numerous programs that can often be incompatible with each other, so the bug can be caused by their mismatch. In addition to that, most common causes of bugs include: human factor, insufficient or inaccurate developer-client communication, unrealistic job deadlines, poor coding practices, poor software design, defects in debugging tools, and insufficient or lack of testing.
The main risks associated with code errors are malfunctioning of certain security features of the program (and thus the web site), which can lead not only to a “crash” of the web site, but also to unauthorized access to the data or corruption of the database.
The validity of the code is a basic element necessary for the normal functioning of every program, and therefore every website. If there is a code error, it will affect the smooth functioning of the website, whether it is its appearance, searching or overall operation. If this happens, business is faced with a tarnished image and potential economic losses, especially if it is a web shop.
Fixing damages from hacking
- without loss of existing data -
Nowadays, websites are increasingly targeted by hackers. The damages that such unauthorized access to the website can do can be great and range from slowing down the website to “crashing” the website and disappearing from the internet.
Repairing a hacked website includes:
- Repairing a hacked database (unsecured database is the most common target for hacking),
- Removing unwanted hacking tools inserted into web site. Such tools allow hackers to re-gain unauthorized access to the web site, in case they are discovered, effectively keeping the “back door” open,
- Eliminating automatic sending of emails via web site (spam emails can cause a web site to be marked as potentially dangerous and blacklisted by various email providers),
- Restoring website’s status as secure with Google and various well-known cyber security companies, which have their own blacklists of potentially dangerous or hacked websites – “cleaning” the site from hacking content and restoring the status of the site as safe for users.
Security breaches, a.k.a. hacking, is gaining of unauthorized access to the website or the unauthorized takeover of the website, due to security flaws of the website. As a result of hacking, malicious content (content that was inserted by the hacker onto the website without permission) may appear on the website. Hacked content can have a negative effect on website’s search results rankings and can potentially install malicious software on visitors’ devices.
Website security is one of the key points and requires regular maintenance and updating to keep the website running smoothly. If the website is not maintained on a continuously, it may become a subject to hacking, potentially exposing the site owner to large financial losses as well as loss of reputation and customer trust, which will reflect on his business.
Website hacking can have a number of serious consequences for the business of the website owner. Hacking can adversely affect the company image, cause the damage that the company would be legally liable for, cause loss of sales and have negative financial consequences for the business, or negatively affect customers’ trust.
Unauthorized access to the personal and website’s sensitive information may lead to the deletion, copying or modification of the data accessed by the hackers. Types of information that hackers are usually interested in are: business confidential information, including email and financial information, and customers’ credit card information.
Loss of data on the website can jeopardize business acumen of the company for weeks or months. Disruption to a website caused by hacking can cause customers to believe that the company is performing poorly and thus lose trust in the website owner’s brand, product or service.
