By Prometteur solutions 19 Min Read

What is Ethical Hacking?

Synopsis claim that “Ethical hacking involves an authorized attempt to gain unauthorized access to computer systems, application, or data.” Ethical hacking is authorized simulated cyberattacks against a system, application or network to evaluate security vulnerabilities. In most cases, these are vulnerabilities that malicious actors can exploit.

Certified security professionals perform ethical hacking using controlled methods. Their job is mainly to identify weaknesses before actual hackers and criminals uncover and potentially leverage them for malicious intents. The malicious intent can fall under things like data theft, service disruption or financial fraud.

The core concept behind ethical hacking is preemptively uncovering IT infrastructure vulnerabilities through tools and techniques that real attacks employ. By taking an attacker’s perspective, organizations gain deeper insights into where existing security controls may have gaps while validating how effectively automated threat detection/response solutions function.

Ethical hacks may target public-facing assets like websites and APIs up to internal corporate networks and devices.

The authorized simulations in ethical hacking determine how far pen testers can infiltrate within some rules of engagement before detection and ejection. The exercise usually leads to critical findings that help in prioritizing risk severity.

Different Types of Ethical Hacking

Here are some of the main types of ethical hacking:

1. Website Hacking:

This involves finding vulnerabilities in a website’s code, web applications, databases or servers. These are vulnerabilities that enable cybercriminals to steal data, deface content or take down the site.

Website hacking probes for issues like SQL injection flaws, cross-site scripting bugs, weak authentication etc.

2. Network Hacking:

Penetration testers attempt to circumvent network perimeter defences like firewalls to gain unauthorized internal access. Once inside, they assess vulnerabilities across connected systems and sensitive data stores.

The goal of network hacking is mainly to compromise network security protections.

3. Mobile App Penetration Testing:

This type of hacking uses penetration testing methods to find weaknesses in mobile apps client-sides in the mobile code as well as the API endpoints connected to backend databases/services.

Pen test assesses authentication protections, improper data storage on devices and overall app security architecture. 

4. Social Engineering:

Social engineering hacking type tests human vulnerabilities rather than technical ones.

With this method, pen testers craft targeted phishing emails, fraudulent phone calls, msgs and physical entry attempts to trick internal staff into divulging passwords or enabling system/building access. It is a testing technique that gauges employee security awareness. 

5. Physical Penetration Testing:

Ethical hackers physically access or attempt break-ins at facilities to uncover weaknesses. These are around door locks, badge access systems, surveillance monitoring, secure areas etc. that are open for criminals.

The variety of ethical hacking assessments allows organizations to probe the full spectrum of human, physical and digital vulnerabilities threatening operations, IP and data security today from all attack vectors and shoulders.

Importance of Ethical Hacking

  1. Identifies Unknown Security Gaps:

Ethical hacking uncovers vulnerabilities and misconfigurations that automated scans or audits miss. Pen testing finds subtle weaknesses in custom apps and infrastructure that would otherwise persist indefinitely as secret liabilities.

  1. Validates Effectiveness of Existing Security Controls:

Ethical hacking reveals where existing tools and teams may be failing to stop attacks and provide visibility. It gauges the whole cyber preparedness. 

  1. Prioritizes Remediation Roadmaps:

The risks exposed through ethical hacking can be segmented by severity and asset criticality. The segmentation can fuel data-driven mitigation roadmaps correcting identified issues that are systematically based on potential business impact.

  1. Fulfills Compliance Requirements:

Many industry regulations and standards like PCI DSS explicitly require comprehensive penetration testing on an annual basis. They use this to maintain compliance status. In other words, ethical hacking is a sure way of satisfying auditors.

  1. Hardens Security Posture:

The sum result of ethical hacking activities significantly enhances resilience against real attacks. This is because it operates by addressing shortcomings revealed under controlled conditions. It is a reliable technique for strengthening barriers and response capabilities before disasters strike.

Ethical hacking plays an invaluable role. It discovers overlooked exposure points. It validates existing defences as well as defines improvement priorities. Also, ethical hacking fulfils governance needs to fundamentally advance enterprise cyber protections now and into the future against ever-evolving threats.

Risks of Ethical Hacking

There are several risks of ethical hacking. We have categorised them under these major three; legal and ethical considerations, potential for misuse and negative impact on reputation.

While ethical hacking provides enormous cybersecurity and risk management benefits, the concepts and realities are not without risks.

  • Legal and Compliance Risks

If you do not scope tests carefully, certain penetration testing activities could overstep legal bounds. They may also violate laws or introduce new compliance risks for the client.

Ethical hackers must exhibit transparency and clients must contractually acknowledge approved testing parameters upfront. This is to avoid allegations of malicious illegal behaviour after the fact. Firms also want assurances around rigorous security protections safeguarding any sensitive client data found.

  • Potential Business Disruption

There are isolated instances where even authorized testing accidentally impaired systems or deleted key data which interrupted client operations.

Leading practices around isolated test environments, data preservation, contingency plans and experienced staff minimize disruption risks greatly. But you still must consider impacts depending on current IT stability levels. 

  • Reputational Exposure

If the public somehow exposes an ethical hack without proper context, companies risk misperceptions and false assumptions.

Prompt breach notification and emphasis on the authorized controlled nature of tests counters this. Still, some PR risk persists and requires planning, given ethical hacking’s controversies in public perception at times.

Potential for Misuse

If you do not properly validate ethical hackers’ backgrounds and intentions, testing talent could misuse authorized system access. This can be for malicious theft or destruction.

This calls for the need for firms to thoroughly vet pen tester qualifications, conduct reference checks, and establish contractual constraints on data handling before engaging in ethical hacking services.

Ethical hackers need to provide transparency by detailing specific testing techniques and tools to be used as well.

What are other potentials for misuse?

  • Oversight Around Testing Activities

Failure to monitor ongoing authorized hacking tests could enable excessive access permissions or objectionable methods that exceed approved scopes.

Define test duration timeframes and implement tooling providing visibility into tester activities during the engagement.

Ethical hacking teams should provide continual progress reporting and disclose new findings in real time to ensure proper oversight.

  • Unanticipated Business Disruption

There is a small risk that even well-intended, properly scoped penetration tests could still inadvertently delete or corrupt business-critical systems. There may also be issues with data and operational interruptions.

The best way to handle this is to isolate testing from production infrastructure and mandate contingency planning for worst-case scenarios. Also confirm data preservation and backup protocols are working as expected.

  • Reputational Exposure

If made public without proper context, ethical hacking engagements can prompt false perceptions of an actual malicious security breach occurring.

Develop a communication plan to reinforce. Ensure that activities involve above-board authorized testing, not actual criminal cyber-attacks. Emphasize security enhancements based on discoveries.

In essence, while extremely beneficial overall, organizations can further minimize any potential ethical hacking risks by vetting talent thoroughly, implementing layered oversight procedures and planning for unforeseen technical faults or public relations challenges requiring response.

Negative Impact on Reputation

It is dangerous to sometimes reveal ethical hacking practices to the public. This is because it can prompt assumptions that there are actual security breaches due to vulnerabilities. This may negatively impact brand reputation and trust.

To counter this, thoughtfully prepare PR statements emphasizing the controlled, sanctioned nature of activities should inquiries arise. Reaffirm that ethical hacking aims to ultimately strengthen defences and customer data protections well beyond current levels.

Here are other negative impacts on reputation

  • Loss of Customer Trust

If live production data gets exposed publicly in any manner tied to ethical hacking tests, affected customers may understandably lose trust in the organization’s ability to safeguard information securely. This makes clear guidelines around strictly utilizing anonymized data sets and never actual customer data critical. No exceptions or oversights can happen on this front – ethical hackers must protect all sensitive materials.

  • Damages from Overzealous Testing

Occasionally overeager or inadequately supervised testers bring down systems and resources through digital or physical means.

You can always build in tested rollback protocols and monitor activities closely through dashboards tracking tester levels of access. Constraints must be put in place to govern when more aggressive techniques are applied. 

While ethical hacking drives security progress, firms must temper activities with carefully constructed ground rules. They must also consider close performance monitoring and prepare public statements. These are to counterbalance reputation, trust and operations risks requiring conscientious mitigation.

As the practice of ethical hacking grows to meet intensifying cyber threats, so too have governance models. Especially when it relates to ensuring proper conduct and consequences. Both binding laws and voluntary ethical guidelines require close adherence by penetration testers to carry out their vital mission responsibly.

Laws and Regulations Impacting Ethical Hackers

Depending on regions and sectors, ethical hackers must comply with various federal, state and industry-specific regulations. These regulations set legal standards around authorized testing activities. These include mandates like: 

  • Gaining explicit signed permission to perform tests to make protected system attacks legal
  • Full confidentiality when handling client data and strict limitations on retention use
  • Ceasing all test activity upon customer request
  • Using minimal system disruption principles during test execution
  • Revealing all hacking methods and tools that will be utilized

Additionally, general data protection regulations greatly constrain the exposure of personal information related to people in applications or databases. Since these data may get accessed during tests, ethical hackers must protect sensitive materials.

Key Ethical Guidelines for Ethical Hackers

Major hacking associations like the EC-Council have published voluntary ethical standards centred on principles of duty, responsibility, honesty and integrity. They all provide best practice guardrails.

These ethics rules compel testers to:

  • Serve the public good over personal gain
  • Maintain high levels of proficiency across security domains through continual skills development
  • Avoid unnecessary harm through narrowly-scoped penetration tests
  • Be transparent regarding qualifications, capabilities, tools and reporting
  • Protect confidential client information obsessively
  • Declare any conflicts of interest that may introduce bias

There should be clear mutual understanding represented by signed legal agreements which will play pivotal roles in upholding ethical tenets. The contracts solidify informed customer consent around planned test strategies, scope, data handling and more. They provide recourse if violations occur.

Defining these terms early prevents confusion down the line regarding hacking activities or outcomes that erode trust.

So, ethical hackers balance overlapping constraints across cyber laws, ethical codes of conduct and customer contracts. They also ensure that all parties clearly understand the bounds to operate within during sensitive security evaluations. This promotes responsible and advanced organizational security postures.

How to Become an Ethical Hacker

To become an ethical hacker, you may need to commit to the following; specialized education, hands-on skills training, respected industry certifications and continual learning to operate effectively in defending organizations’ digital assets.

Following this part, penetration testers have an exciting career path contributing to the advancement of cybersecurity.

Let us give a breakdown.

Currently, damaging data breaches are accelerating across industries. This means ethical hackers will continue to see no shortage of career opportunities within cybersecurity consulting firms.

They will also see opportunities in Managed Security Service Providers (MSSPs), management consultancies and corporate IT groups seeking robust penetration testing defences. Also, more opportunities abound in safeguarding critical digital assets against escalating global threats.

Ethical Hacking Tools

Like with other complex technical disciplines, ethical hackers rely extensively on advanced software toolsets. It uses these tools to systematically identify security vulnerabilities threatening client organizations.

Let’s explore primary ethical hacking tools categories.

  • Specialized Penetration Testing Tools

Skilled hackers use customizable pen testing frameworks like Metasploit and CANVAS. These are tools that enable the creation exploits, payloads, shellcodes and scripts that safely simulate various attack techniques against target environments.

  • Automated Vulnerability Scanning Tools

To efficiently detect network and system misconfigurations at scale, many tests leverage vulnerability scanners like Nessus and OpenVAS.

These are tools that probe Internet-facing infrastructure for the following; known software flaws, patch gaps, app bugs and credential weaknesses exploitable for access. Scans also highlight remediation advice.

  • Password Cracking Tools

For assessing authentication scheme resilience, ethical hackers employ password-cracking tools similar to what criminals use like John the Ripper or Hashcat.

These ethical hacking tools are for rapidly guessing and decrypting stolen password lists. They work through brute force, dictionary and rainbow table attacks.

  • Network Mapping and Discovery Tools

Early in engagements, mapping the full attack surface is vital. So port scanning tools like Nmap and network sniffers like Wireshark see heavy use in finding; live hosts, open ports, service versions and operating systems powering networks ethical hackers target with further probing for weaknesses. 

The combination of these tool types into ethical hacking toolboxes allows for methodical vulnerability assessments and tailored penetration tests matching real-world threats to harden security postures.

The Future of Ethical Hacking

Increasing Demand Growth

With cyberattacks exponentially rising yearly, demand for skilled ethical hackers will see massive growth. At least through the next decade across both public and private sector organizations urgently needing deeper security protections will lead this trend.

We predict that more and more professionals will enter the field.
