I am completing a bachelor’s degree in cybersecurity at Old Dominion University, and my professional goal is to continue developing as an information technology and cybersecurity professional. Through my coursework, internship experience, and current position as an IT Support and Security Technician, I have developed practical abilities that connect technical knowledge with real workplace needs. The three skills highlighted in my ePortfolio are documentation, troubleshooting, and automation. I selected these skills because they represent the work I perform most consistently and demonstrate how I can communicate technical information, resolve technology problems, and improve the efficiency of recurring processes. These abilities are valuable in both IT support and cybersecurity because organizations need professionals who can identify problems, implement reliable solutions, and clearly document what was done.

Documentation

Documentation is the ability to organize technical information so that another person can understand, verify, and repeat a process. It is essential in cybersecurity and information technology because technical work must often be communicated to users, other technicians, managers, and auditors. Effective documentation also promotes consistency, reduces errors, preserves institutional knowledge, and provides evidence that security requirements have been addressed.

One artifact that demonstrates this skill is a knowledge base article I created for resolving a corporate wireless connection problem. During the original incident, I determined that an existing Windows wireless profile was preventing the computer from completing a fresh 802.1X authentication. After removing the profile and validating the organization’s authentication certificate, I successfully reconnected the workstation. I then converted the solution into a structured article that explained how to recreate the wireless profile, confirm the certificate, verify connectivity, and escalate the issue if authentication continued to fail.

A second artifact is my laptop imaging and workstation deployment documentation. I organized the major stages of device preparation, including Windows configuration, software installation, account setup, security controls, updates, and final verification. This documentation created a repeatable process for preparing computers and reduced the possibility of missing an important step during employee onboarding.

My third artifact is cybersecurity compliance evidence that I helped collect and organize for CMMC projects. This work included documenting software inventories, device assignments, privileged accounts, security configurations, and the locations of supporting evidence. I had to ensure that the information was accurate, clearly labeled, and connected to the applicable security requirement.

These artifacts show that I can write for different technical purposes. In a professional environment, my documentation can help technicians resolve incidents more efficiently, support employee training, improve service consistency, and provide evidence during security assessments or audits.

Troubleshooting

Troubleshooting is the systematic process of identifying the cause of a problem, testing possible explanations, implementing a solution, and verifying that normal functionality has been restored. This skill is valuable because technical symptoms do not always reveal their actual cause. Effective troubleshooting requires patience, logical reasoning, careful observation, and the ability to avoid making unnecessary or disruptive changes.

The corporate wireless incident is also one of my strongest troubleshooting artifacts. I began by confirming that the workstation could connect to a guest network but could not connect to the secured corporate network. This helped narrow the problem to the corporate wireless profile or its authentication process rather than the computer’s wireless adapter. I restarted the relevant Windows services, removed the saved profile with the netsh command line utility, reconnected to the network, validated the legitimate certificate, and confirmed that the device had regained connectivity.

Another artifact involved a shared network printer that appeared under an incorrect model name on a user’s computer. After speaking with the requester, I learned that the main problem was not simply the printer’s displayed name. The old printer entry was sending jobs to a different physical printer. I removed the incorrect connection, installed the intended printer using its network address, set it as the appropriate printer, and printed a successful test page. This experience demonstrated the importance of clarifying the user’s actual goal instead of treating the original request as a complete diagnosis.

A third troubleshooting artifact was a mapped drive access request involving file server permissions. I identified the correct file server, verified the intended user, reviewed the folder’s security settings, and updated the appropriate access group without granting broader permissions than necessary. I then checked that the authorized users retained access and that a former employee was removed from the relevant group.

In the workplace, troubleshooting allows me to restore services while minimizing downtime and security risks. My approach is to gather evidence, narrow the possible causes, make controlled changes, and verify the result before closing an incident.

Automation

Automation is the use of scripts or other technologies to perform repeatable tasks with limited manual intervention. In IT and cybersecurity, automation improves efficiency, promotes consistency, and reduces human error. However, useful automation must also include safeguards, logging, and verification so that it can be used reliably across different computers.

One artifact demonstrating this skill is a hardened disk cleanup script that I developed for remotely managed Windows devices. The script performs approved cleanup activities, records its actions, and uses Windows servicing tools to reduce unnecessary component files. I also incorporated checks so that the result could be measured instead of assuming the cleanup was successful. In one case, the script restored a device’s available disk space to more than 12 percent.

A second artifact is my collection of standardized application installation scripts. I created scripts for applications such as Google Chrome, Mozilla Firefox, Adobe Acrobat Reader, Zoom, and Microsoft Project. These scripts use consistent installation procedures, generate logs, and check whether the software installed successfully. They make application deployment faster and more dependable than manually installing each program on every workstation.

My third automation artifact is a browser and application cache cleanup script. I designed it to clear selected temporary files without unnecessarily deleting user information. Developing this script required me to distinguish between disposable cache data and files that should be preserved. This demonstrated that automation requires both technical scripting ability and an understanding of the risks associated with modifying user devices.

Professionally, automation enables me to handle recurring support tasks at scale. It also allows other technicians to perform standardized actions, improves the quality of deployment records, and gives the team more time to focus on incidents that require human analysis.

Describing My Skills to an Employer or Supervisor

My documentation skill comes from translating technical work into instructions and records that other people can use. For example, after resolving an 802.1X wireless authentication problem, I created a knowledge base article covering the solution, validation steps, and escalation criteria. I have also documented workstation deployments and helped organize cybersecurity compliance evidence. These experiences show that I can communicate technical information clearly to both operational and security focused audiences.

I developed my troubleshooting ability through coursework and hands on IT support. I use a structured process of gathering information, isolating variables, testing controlled solutions, and confirming functionality. For example, I traced a printer issue from an inaccurate device listing to an incorrect network connection and then installed and tested the correct printer. I can solve immediate problems while also considering access control, business impact, and future prevention.

My automation skill is demonstrated through the Windows scripts I have developed for software installation, cache cleanup, and disk space remediation. I build safeguards, logging, and validation into my scripts so that their results can be reviewed. These tools have reduced repetitive manual work and standardized common support processes. I would bring that same focus on efficiency and reliability to future IT or cybersecurity responsibilities.

Strongest Skill Reflection

Troubleshooting is currently my strongest of the three skills because I use it almost every day and it supports both documentation and automation. I have developed it through cybersecurity coursework, my previous IT internship, and my current support position. The corporate wireless authentication incident contributed significantly to my growth because it required me to distinguish between connectivity, device, profile, certificate, and authentication problems. It also led me to document the solution for future technicians. In my future career, I plan to apply this skill in security operations by investigating alerts, analyzing evidence, determining whether activity is malicious, and selecting an appropriate response.

Applying My Skills Going Forward

After graduation, I plan to continue developing these skills through professional IT and security work, hands on security operations experience, and additional certifications. I especially want to expand my scripting abilities and learn how to automate security investigations and response tasks. Continuing to document what I learn will allow each new troubleshooting experience to become reusable knowledge for myself and the teams I support.
